What do you call a computer strapped to the back of a monitor?
Apparently it’s a AiO computer… 😕
I found this strange little thing on bid for £4.99, and there really wasn’t all that was said about it. No specs, no model number, nothing. Just “It turns on” but “It has a password” therefore it was being sold for spares and repairs.
A BIOS password is extremely easy to bypass; usually it’s just a matter of moving a jumper and turning the computer on, or just taking out the CMOS button cell battery (Usually a CR2032).
I figured at £4.99 (Plus £9.99 shipping) there really wasn’t much to lose, and took the plunge, putting in a bid for it. My max bid was £20; I wasn’t really willing to spend more than £29.99 on it, because it was a curiosity more than anything, and I had no idea what the specs were, at all. I was surprised that no one else was interested in it. He claimed he had brought a load of them from a joblot and was selling them individually on eBay. It was advertised as coming with the power cables and VGA cable, but other than that; there wasn’t much.
Of course after I bought it, the seller started charging £14.99 for them +£9.99 Shipping.
Item: Ex-School AiO PC (Parts and Spares)
Price I paid: £4.99 Shipping: £9.99 (Courier) Total Cost: £14.98 Came With: A heavily modified Windows 7 Installation. This topic won’t be as long as the others because there’s not really much to talk about.
When I got it, I was impressed with the condition of the machine; I have to admit I had reservations about the overall build quality, especially when one of the CEO’s for Viglen back in the day was Bordan Tkachuk who is perhaps famous/infamous for saying:
He’s completely wrong, of course, in more ways than one. So I wasn’t inspired to say the very least, as the man seems to know nothing about basic knowledge for people who are supposed to be working in Technology.
Anyway, the condition of the machine was pretty good, and when I booted it up there was indeed a BIOS Password. Removing this was a simple matter of opening the case and flipping the jumper which was readily accessible. When I turned on the PC it told me that the password had been cleared and that I needed to reboot the machine with the jumper in the correct position.
I did that, and I was presented with not Windows Vista (Which is what I was sold) but Windows 7 (Enterprise, I think) and it was very heavily modified. It seemed to have come from a primary school, and thus it was expecting a domain server on the network that it couldn’t find.
I’ve spoken about this before in regards to school computers and servers. Quite often there are no sensitive files on these machines because the files aren’t stored on them. Instead they’re stored on a kind of ‘Profile’ on the server that allows you to log into any authorised computer on that network, and have your files/documents travel with you when you log onto that computer. This is because the files aren’t stored on the actual computer - it’s just a workstation. The files are stored on the actual server. So there wasn’t any sensitive files on this device - I knew this before I hacked my way into the OS.
Once I was in the OS (Using a backdoor user account that was created on the machine probably during setup) I confirmed that there was nothing groundbreaking left behind. Not a single document, or text file, incriminating evidence, family pictures or otherwise. I ended up wiping the hard drive and put Windows 10 on it - although I some issues after I opened it up again and took it apart. Which I will get to in a moment. I had rolledl back to Windows 7 whilst I was sorting these issues out, but eventually I diagnosed the fault and put Windows 10 back on it.
And it works perfectly.
Before I get into it this time; let's find out what I bought:
Viglen Genie AiO PC (With Intel DQ35JO Motherboard)

VGA Output DVI Output Upto 256MB shared memory PSU: 1 x Enhance 250W Power Supply (80 Plus Bronze Efficiency Sticker) Model ENP-7025C HDD: 1 x 80GB (Originally: WDC WD800AAJS-00WAA0, 80GB, 7200 RPM, SATA II) Monitor: A 4:3/5:4 Ratio Maxdata Belinea 17” Display with USB Passthrough and built in speakers (They’re awful). Sound: Realtek High Definition Audio (Realtek ALC268) Stereo Speakers Integrated with Monitor (I don’t know the wattage, they’re absolutely atrocious though). For £4.99 ($6.30 USD, $9.09 AUD, €5.57 EUR, $8.35 CAD, at the time of writing) the specs are really not bad at all! I could easily flip the computer on it’s own for quadruple the price, which makes back the shipping and I get a free monitor for my troubles. It could make a fantastic computer for a child who uses it for homework and basic word processing, as well as light internet usage.
I think it’s got reasonably competent connectability; a gigabit ethernet port is a major plus with this machine, which is on the back with a firewire port, six USB2 ports a VGA and DVI port as well as microphone, headphones/speakers and a lineout port. On the front it has two USB2 ports, a headphone jack and a microphone jack.
However; as I expected with Viglen - which might as well mean buy the cheapest possible components and throw it all into a computer case to see if it sticks - the internal engineering is absolutely abysmal. At 5.1KG for the computer unit alone, (5164g) this is not a lightweight. Cable management was an absolute nightmare and no thought was put in to the case either.
Take a look at the inside:
This is after I cable managed it.
The major problem with this machine is heat, and on that note I’d love to meet the absolute spanner who thought it was a good idea to put a PSU directly above in near contact to the Intel 82801IDO Southbridge heatsink! It gets to temperatures in the region of 92oC hot and it cannot dissipate the heat properly because there’s no airflow over that area, and to top it all off the PSU is generating a generous amount of heat as well. In addition; the HDD is right on top of the RAM (Also generating a good amount of heat). The Power distribution of the system seems precarious at best.
The thermal paste was god awful and was causing several Thermal Cutoffs (Where the machine would outright shut down to protect the CPU), not allowing me to do an accurate test of the CPU temp before thermal pasting. But in fairness most OEM’s have poor quality thermal pastes. I replaced it with my standard Arctic Silver 5, but under the current configuration it’s temperature is erratic under load:
But at least it’s not cutting off outright.
This is this machine’s biggest enemy, and I think I might know of a few solutions to help with it. The CPU fan seems to be an intake, where as the PSU fan and the one opposite are output fans.
Picture I took whilst I was dismantling it to replace the Thermal Paste:
After stabilising the machine, I did some cable management and tied it up. I did try replacing the HDD with a higher capacity one, however I had lots of errors happen when I did that, such as “Memory_Management”, and so on until the computer just outright failed to detect any other hard drive other than the 80GB one. You’d hear it power up, and then it’d power it down repeatedly - and this was with a good hard drive (Because I use it in the HP AiO now and it’s absolutely fine) This is why I suggest that the power distribution is precarious… Perhaps and SSD will do fine in this system - were it not for the heat issues I’m finding. I do not like subjecting SSD’s to more than 35oC of heat, certainly no more than 45oC if I can help it.
That said. Despite the system running much hotter than I’d personally care for, it does run now, and I’ve not had a problem with it. But perhaps I will run it in the winter when I don’t want to use the heater in the house.
I believe this motherboard could be translated to a different case and utilised to its fullest extent. With a decent cooler on the CPU there is plenty of upgradability here; especially with those SATA ports (Red one is designed for External SATA).
There’s not really that much more to say about this machine, it was extremely cheap and you get what you pay for, however individually, the parts are worth more to me than the whole machine. Why I can use the RAM with another old machine I have, and the CPU with the next item I will be featuring. If you do have any questions please leave them below!
I’ll close with some AIDA64 Benchmarks, but I will be comparing them to my next ‘Shit I’ve Bought on eBay’ as the next machine is comparable as it has the same CPU:

Next on: "Shit I've bought from eBay" - ACER Veriton L670G PC
What use is an all in one PC, especially by HP of all OEMs?
Watching YouTube or listening to music in the Kitchen, of course. Naturally.
I found this one whilst browsing on eBay. It was marked down as broken; specifically “The Screen is Cracked” but it otherwise powered up. It included everything internally - HDD, RAM, processor, etc. But did not come with a power pack.
There was no excitement with this one, I put down a maximum bid of £20, with the intention of taking it up to £30, and I pretty much won it at the end of the seven day listing for the listing price of £5 +£8.99 Shipping. Although I knew I would need to make other purchases, so £13.99 is not all I paid for it.
Honestly I was surprised to have won it as over the last few days I kept getting bid sniped on everything (Where someone comes in and put in a bid with a few seconds to spare so you can’t react to it) so I didn’t expect to win it. But I did and I was ecstatic. Immediately after paying I put in a call to a well known supplier of odds and sods of computer parts to see what kind of deal he could offer me for a HP Pavilion AiO LCD Panel; after taking the part number, he told me he could get one for £39.99. I thought that, that was a reasonable price, but I said that I was going to do some shopping around first. Credit to this supplier: He did say that if I can find a cheaper price to contact him and he’ll see what he can do.
A few days later I found one for £17.49 on eBay; that was pulled from a fully working MS215UK model HP AiO PC. Now these OEM computers sometimes use the same components as similar models, such as it were I found out via HP’s Partsurfer that the same LCD Panel is used in the MS215UK as the MS228UK and a handful of other HP AiO’s. It was a risk; but I decided that it was worth going for it.
After I had gotten the AiO, I noticed that there was no power supply; so I needed to shop around for one. I found an aftermarket one for £10.49 and after testing it on the computer I was able to turn it on. However my problems started with it, which I will explain later. So I went and purchased a genuine power supply for £22.90, and I have sent off the aftermarket one back to the seller for a refund.
There are several items that made this possible.
Item: HP Pavilion MS228UK All in One Desktop PC
Price I paid: £5.00 Shipping: £8.99 (Courier) Total Cost: £13.99 Came With: An entire family’s private data including pictures, bank information, passports, password files, pay slips, tax information, memes and music. Item: HP Pavilion AIO MS215 LCD panel

Price I paid: £22.90 Shipping: Free (Royal Mail) Total Cost: £22.90 Came With: Nothing. Grand Total Cost: £54.38
As you can see from the above image; I was successful in repairing the AiO PC. I am quite confident at repairing computers and I have been doing off and on for over two decades. My first computer that I repaired was when I was five or six years old; and it was at school. The school teachers knew I was great with computers - it seemed to be this ‘Natural Talent’ I had, and I remember telling them frankly “I get on with computers better than I get on with people.” Which is still true today. I had always owned a computer (My first ever being a Basic Amstrad CPC464) so when I was presented with a C drive error and my teacher had no idea what was wrong with the computer, I told her that I could fix it; I knew how to put Windows into DOS and perform a ‘Scandisk’ of the C drive; which found errors and fixed it. When the computer booted up afterwards it worked perfectly. In my primary school after this incident; I became the primary school’s defacto IT technician as they didn’t have a real one; and back then things were much simpler. If there was a problem with a computer somewhere in the school; that teacher would end up sending a student to come to the class with a note to the teacher, and I’d be excused to go fix it, although I always had time limits (10 Minutes, 20 minutes, etc). This all changed when a new headmaster came in, and I don’t think this headmaster liked me very much; but that’s a different story. My point is; from a young age I’ve been learning and studying computers. Playing around with them at home trying to break and repair them on a software level and learn how they work. Reinstalling Windows, and DOS, playing around with the various settings and such. Back then there was no Internet in the house so I had to teach myself everything.
It’s precisely those lessons that I applied here, I have a set of diagnostic steps which I use to identify and repair faults, then I fix them. For a start on the listing I knew the screen was cracked - common fault on LCD monitors. Usually this is caused by a person; especially if the screen is cracked. I knew that there is no point in repairing the actual panel; it’d need to be replaced. I have never had a HP AiO before; so I opened it up.
First of all I opened the two panels on the back - one was for the RAM, the other was for the Hard Disk Drive (HDD) but had a screw in there that held the CD drive in place. I ejected that and set this components aside; I took the HDD out of it’s caddy and put it into a hotswap bay on my PC only to discover that it had a full Windows installation on it.
OH DEAR. OH DEAR… We’ll come back to that.
Going back to the actual computer now; when I finally got it opened, I was presented with a shocking display:
The whole system was caked in dust, and I knew instinctively that if this thing had an integrated GPU; on the same copper pipe as that one heat sink (Which I could already tell was infinitely likely) then there was going to be a problem with the GPU on this, which is a common fault caused by overheating that the original XBOX360 owners will know all too well.
Opened up the metal panel cover the motherboard, disconnected the fan and then unscrewed it before pulling it away from the board. I was then able to see how clogged the heatsink was:
Yeah - that’s not a good thing. There is very few fins that the air can escape through. On top of that, dust can be an insulator; and that coupled with heat is not good. I thought for sure - this computer is going to have suffered overheating damage. This wasn’t good. I was not going to boot this up in this state. Taking this off of the motherboard was an absolute pain in the arse to be quite honest with you.
The problem is, is that it was practically glued onto the CPU. There was such a tight seal between the two with the thermal paste between them which had hardened that I actually delidded the AMD processor under it, which I did finally remove it. I cleaned up all the thermal paste that was on it and replaced it immediately with Arctic Silver 5 (Including the processor chip under the IHS), and then cleaned the heat sink with some compressed air, and an old tooth brush with Isopropyl Alcohol to clean it up. When I was satifiied I attached it back to the board and then I looked at the fan, and took it apart.
The fan was in a shocking state as well. I’ve cleaned up desk fans before and I’ve noticed with all of them that if there is a lot of dust built up on the blades, the amount of air that they push out seems to be diminished. If they’re cleaned up they noticeably push out a lot more air. I haven’t scientifically tested this, but it is something I have noticed, and I wonder if the same principle applies here.
Here is it after just a basic cleaning:
I finished up on it and made it look as good as brand new.
Taking a look at the motherboard; I could see no obvious signs of capacitor wear and tear; nothing exploded or bulging:
But I did notice that as I suspected the GPU was on the same heat pipe as the the CPU, all on one heat sink… Oh boy.
USB Ports Ethernet Port (I think it only does 100Mbps, I’m not sure) Power Port SATA Wireless Card SD Card RAM Slots (4GB Max, DDR2) Central Processing Unit Graphics Processing Unit Monitor Connection I knew straight away that the GPU was going to be iffy and would need reflowing (The act of heating up the chip to ‘reflow’ and refresh the solder) which was extremely risky. In everything I had tried this on, I had failed and made things worse - I had NEVER successfully reflowed/reballed a chip a before… So I was hoping that I didn’t have to.
I didn’t take any pictures replacing the screen; but needless to say it was a tedious and careful process. I had to remove a lot of screws and connections, and carefully note what I had done so I could reverse it when I wanted to put everything back together again.
Taking my time, and being as careful as I could, I attempted for the first time ever to put in the screen; and when I did it and had almost everything back together, I breathed a sigh of relief. I powered on the machine and saw!
The power light came on, the fan span up, but then everything went dead, the power light was still on and it was powered up, but nothing appeared on screen. SHIT! I thought. I then tried to diagnose the problem, and according to a HP forum post I read this was likely to be a power pack failure.
At this point I was using the after-market power pack and I tested the power output through an AMECal ST-9905 (As used by BigCliveOnline, one of my favourite YouTubers) and found that the output voltage was at 16.32 and dropping (The last test I did with it, it was at 14.59V). The computer needs 19V to operate, and the amperage needs to be 4.79A which surprise - surprise this Power Supply wasn’t and was all over the place.
I started a refund and returns for this power supply and got a genuine HP one which took some finding as they’re quite difficult to come by at a reasonable price nowerdays. When that arrived I plugged in it; and booted it up.
The screen came on, and everything seemed to work, for a moment. Then everything went dead again. There was another problem; and after a lot of diagnosing and avoiding what I knew in the back of my mind to be true, I came to the conclusion that the GPU needed to be reflowed… I don’t own a heat gun…
I do however own one of these bad boys from my weed smoking days:
Let there be fire
It’s basically a lighter that’s more like a fucking mini-blow torch. Risky… Very fucking risky. This has the tendency of quickly setting fire to things, and so I wanted to be extremely careful with it. Turning it on, I ran it over the chip for thirty seconds, making sure to keep it moving, and not too close to the chip as I moved it around making sure to cover each part of the chip equally. Afterwards; I hovered my hand over it afterwards to feel that it was hot, but I did not touch it - and nor should I. I let it cool down on it’s own without touching it any further for the duration of an episode of Star Trek the Next Generation and put the heat sink back on…
Oh I also replaced the HDD with a WD Black 1TB Drive, and installed Windows 10 Home.
It worked. To be clear though it only works with the Genuine HP Power Pack; the other power pack has the same problems I described earlier. Therefore I can deduce that the aftermarket brand Power Pack is not fit for purpose. I installed Windows 10 Home, and spent some time setting up the machine, which will be in our kitchen so we can watch things on YouTube, or BitChute whilst we’re in the kitchen - or have music playing.
So now I’ve been through the repairs, and this machine is 100% operational again, let's get right into this shall we?

Yeah; we’ll let's talk about that shall we?
So I rebooted my computer and booted into that windows installation to see that it was Windows 10 Home, upgraded from Windows 7. The user account that logged in, which I will call ‘User 1’ didn’t have a password so I was in - instantly. I then discovered that the hard drive seemed to be taking a long time to do anything. It was at that point I decided to terminate the session as I believed I was looking at a dying hard drive. Long story short: I was correct. I rebooted back into my Windows 10 and took ownership of the /users/ folder, then copied off to my hard drive; I then ran a file recovery program on it, and recovered a massive payload of deleted files that had not been overwritten.
Whilst this was doing that, I had a look at the files I copied over to my hard drive; and oh deary me… This hard drive wasn’t even formatted before being sent to me. In the Users Folder I found five (5) different user accounts; User 1, User 2, User 3, User 4, Admin 1 (I’ve removed the names), and I have permission to share the details of what I found in there, and what happened.
In total I recovered 38GB of information from the drive.
I didn’t find any porn; or porn collections but I’ve not fully gone through everything. What I have gone through and seen on this hard drive is the following:
Lots of family pictures and selfies, including pictures of people using this very computer. Bank information, such as sort codes, account numbers, card numbers and pin numbers for those cards. Scans of passports Unencrypted text files containing: Passwords Pay Slips Tax information Tame Memes One or two spicy memes Music Documents Homeworks, coursework information and so on. Pirated Movies Internet Browsing Histories of 5 people Autocomplete passwords access Their contact information (Names, Addresses, Phone Numbers, Email Addresses, etc) This is why I left the feedback:
And no I won’t be doing that, I'm not that sad.
Within this treasure trove of information I found the names, addresses and phone numbers (And even a passwords text file) of the family and made contact with them. Yes; I called them up, and spoke to the father, which was quite risky. I asked if I could have five to ten minutes of his time, and that I wasn’t trying to sell him anything or do market research. He agreed and I thanked him. I then explained to him why I had called…
I told them that I had brought this computer off of eBay and described the computer to him; I told him that all of their data was still on it's hard drive. The man wasn’t very happy - and I don’t blame him at all. He told me that they had an an accident something got knocked over and smashed into the screen, and they took it to a repair shop to get it repaired. However… They were told that it was beyond economical repair, that it wouldn’t be worth repairing the PC, but they will if they wanted them to; it’d just cost £199.
The father went home to discuss this with his family, however when he got home he found his son setting up a brand new PC that he had brought with his own money (I think he was the one who broke it) to replace the broken one for the whole family to use.
Now that’s sweet, isn’t it? A young person taking personal responsibility for his actions. You don’t see that too often nowadays.
So the father went back to the repair shop and told them “Categorically”, to "Destroy the Hard Drive, and dispose of the PC as you see fit". So to find out this after the fact; you can imagine that they were not happy with the shop to say the very least, and I can’t blame them.
The family were not aware that their PC was sold on eBay either!
I told them that I would be very happy to send the files back to them, via a flash drive in the post - completely free of charge, and I confirmed their address, however they wanted it sooner and so it was emailed to them instead. They were extremely happy that I was able to recover their files and I had sent it back to them, but the father (Admin 1) said it was a little surreal that I called out of the blue and offered to do something extremely kind. Meh; that’s the kind of person I am, I guess. I told them to change their bank pin, and debit cards and passwords as I had access to that information and if I did; whoever’s hands the computer has been in before I got it, could have it too. I also told them that I was able to repair it for about £20; and that this repair shop was nothing short of extortionists.
I sent the files back to them and they have received it and thanked me. They even offered me money for my assistance (£100) which I have declined; although that would have completely paid for this PC and then some.
The hard drive after all this got completely corrupted; and it was clear that there was something going on under the hood. So I pulled up Crystal Disk Info:
Yikes. 9,773 pending sectors (9,773 * (Sector Size(4096 bytes)) / 1024 = KB / 1024 = MB = 38.17578125MB of the drive is unstable) and 15 uncorrectable sectors. I would not use this hard drive for anything at all. Still - I zero wiped it twice and this didn’t change. So I’m inclined to believe that this drive is on its way out. I will not be selling it - so I might play around with it, or take it apart for the magnets, and assign it to physical destruction (I have a place that I can go to that allows you to chuck them into this giant shredder.)
I want to urge everyone here; if you’re selling your computer/laptop then please at least do a proper format (Not a Quick Format), or worse yet don’t just *delete* your files or “Restore Windows from a Factory Image” and call it job done, it most certainly isn’t. Do not be lazy about this. Overwrite that data. So assholes like me can’t come along and recover it; I really can’t stress that enough. In most cases a single pass of random bits will do, but if you want to be sure, 3 passes like with the DoD 5220.22-M is usually a good idea, but if you’re a little paranoid, a 7 pass write like DoD 5220.22-M ECE I guess is alright. But if you’re extremely paranoid - just don’t sell the hard drive, and physically destroy it, and sell/give the rest of the computer. Chances are if you’re reading this, you probably don’t need to be told that.
There are far worse people out there and I can’t tell you the amount of times I’ve purchased second hand hard drives online, that people haven’t properly formatted the hard drives of. I’ve had access to various kinds of sensitive materials that have either been too hot to handle or have been wiped properly by myself. But the stuff I will talk about openly is that I’ve also had access to a company’s customer database which included names, addresses, phone numbers and credit card information of their customers. But most commonly I’ve had access to people's private and personal files, and in one case I got access to someone’s private porn library. Even if you’re taking your computer to a repair shop and tell them to dispose of it- as for the hard drive back! Don’t trust them with it! This is exactly why you shouldn’t.
To see someone actually take data protection seriously and to wipe their drives before selling them is a good thing to me. I actually like that they do it properly. But I always format again; just to be sure, it roots out any bad sectors, and makes sure that the drive is properly cleaned and conditioned, ready for use. You don’t need to use the Gutmann method (35 pass write) because that is most certainly overkill.

Due to the fact that this drive was dying I put a 1TB HDD that I had spare. I thought it was a WD Black; but apparently it’s a Blue. Which is strange because the label is black. Hence the assumption. Either way I think it’s only capable of SATA II, so it’d be a waste of time putting in a SATA III drive.
Despite HP’s reputation for overheating; when I ran AIDA64, and told it to stress the CPU, FPU, Cache and System Memory, I couldn’t get it past 40-45oC. I don’t think any thermal throttling was going on either. The air coming out of the top of the device was pretty much cool and the system was running fine without breaking a sweat. In fact I was concerned that the stress test wasn’t even running. Strangely however despite that kind of temperature the cores of the CPU seemed to be running at about 20-25oC which is about a 20oC (50%) difference to the rest of the CPU. I’m not really sure what was going on here, as I’ve never worked with AIDA64 before. But Prime95 and Speedfan, as well as HWInfo produced the same data. Apparently the maximum operating temperature of the CPU is between 55°C - 81°C so to get what I’m getting - I consider that to be extremely good.
I know the CPU is vastly underpowered (25W) but that is incredible results to me. Especially for a a HP. By this point I had already refreshed the thermal past of the CPU and GPU; when I repaired it. But this is actually highly encouraging. It’s a shame I can’t overclock the CPU. CPUID doesn’t display correctly for this either. The Socket has AM2 printed on it, the CPU is AM2+ (Or AM2 Revision 2) and yet CPUID reports it as AM3:
This small CPU clock of 1.6GHz pretty much reminds me of the crappy netbooks that was quite popular about about ten or so years ago, and the computer does struggle from time to time especially when things are loading up, but that could be a hard drive bottleneck as well as in Task Manager I’d frequently see the HDD activity stuck on 100%, and the CPU would be fine. It might be something I consider later, buying a cheap SSD to slap in there so that it boots up quickly and we can truly use it as a PC-TV. That said it seems to be able to run videos be that from YouTube, BitChute in 720p and the DVD Drive plays our Star Trek and Babylon 5 episodes just fine. So for the purpose I’m using it for, it’s fine.
EcchiDreams loads in the browsers, no problem too. So that’s also good. Although I’m not ever going to sign into EcchiDreams (Because my staff account is a high security account, and I’m not even allowed a duplicate account) and I do not consider this machine to be a high security machine.
For a start; doing a full disk encryption for the system drive is most certainly going to slow it down to a crawl. Secondly I can’t even put in a BIOS level password. Where I showed a picture of the motherboard, look carefully towards the edge of the motherboard in box 7; You can see two sets of two silvery looking contacts, one says “CLEAR PASSWORD” and the other says “CLEAR CMOS”. Instead of hiding this further into the board, where it can’t be easily accessed, all you need to do is remove the memory cover, and press on the two contacts to remove password with your screwdriver to clear the password and boom. Job done. You’re in. I don’t consider this to be a good thing, and is a prime example of convenience defeating security. As this has been designated a low security machine on my network, it doesn’t have access to any network resources such as any of the servers, or the NAS or our computers which means music and stuff needs to be manually loaded onto it via flash drives. It doesn’t have a username or password so you can just turn it on and it’ll go straight into Windows. The USB ports on this machine are all USB 2.0 from what I can tell, which means it’s capable of 480Mbps maximum and there are six USB ports on the device. Four on the back and two on the side.
It also has a built in SD Card reader; which I can honestly see using that instead of putting in DVD’s, or holding music libraries on that and having and SDCard case next to the computer as SDCards are dirt cheap nowadays.
We’ve got this computer set up in the kitchen so that we can watch videos, or listen to music whilst we’re cooking or cleaning up, or just to have a ‘Stereo’ of some sorts, but let's talk about the sound quality shall we?
It’s bearable, but compared to my dedicated set up with the Matrix Mini-i Pro and HE400s it’s fucking awful quality. Watching things that mainly have dialogue isn’t too bad, but music sounds tinny, and frankly like they’re coming out of a set of laptop speakers from 2009/2010. I suppose I shouldn’t have expected much considering A) It’s age B) What it was intended to be used for and C) It's not specialist equipment. Lol
Despite having a sticker over the webcam, I actually disconnected it and left it disconnected (On purpose) whilst I was in there, and I think it’s on the same board as the microphone which was connected too because it’s on the same cable. I’m that type of guy who covers these webcams (And front facing cameras on their phone) for a damn good reason. It is something I have done to every laptop I’ve ever owned, where it’s been included. So I haven’t tested these out, but I am sure if I did it’d be absolute dogshit; given that it’s a VGA Webcam so I expect it to be around 0.3 - 1.3 Megapixels, and it’s from around 2009/2010. It’s a Chicony CNFA09921004171LH (Model: HP CFNA099-A2) (Part: 537546-001) If you’re interested.
Do not count on this machine to play any games; it doesn’t have the processing capability or the graphics power that would be required.
All in all I can say that I like this machine and it will serve its purpose in the kitchen just nicely. What I don’t like about this machine, is that in order to clean out the heatsink and fan, you need to take the whole damn thing apart which isn’t all that easy. But it’s something I will do yearly. I do not want to let this PC overheat again, otherwise I’m going to potentially have to reflow the solder; again. Other than that it’s a neat little thing and everything is very well contained. In my experience I wouldn’t call the internals ‘Desktop Components’ but more like Laptop Components, that’s neither a plus or a negative for me, although it does limit its power. I suspect that I could replace the CPU with a 260u; but I probably won’t, and I don’t know if it can take more than 4GB of RAM; according to the CPU Spec - it can, but according to the PC Spec, it can’t. I don’t have other sticks of laptop sized DDR2 RAM so I can’t test it.
It goes to show that there is a use for these older machines today; although as an everyday working computer? Probably not.
