What started out as a roughly improvised poor-man’s all-in-one PC (See gallery here) hanging off the back of an LCD display has turned in to two detailed schematics painstakingly drafted with the proper measurements ready for the cutting table. Download the schematics below by clicking on the images.

The first one is a modification and refinement of the of the first VESA mount PC using the miniature Intel D201GLY motherboard/CPU. The second one is an all new version that features full size MicroATX support, dual-core processor support, and full-sized PCI-Express support using a 90 degrees angle adapter for a full blown gaming or professional workstation.

Note: This entry is also available as a TechRepublic PDF download.

Mini-PC box: D201GLY with 1 half-height slot and 3 hard drive slots

This box when loaded with 3 hard drives when the D201GLY2 arrives with two SATA and one PATA port and a $15 gigabit PCI adapter would make a killer NAS (Network Attached Storage) and general purpose server. The box with only one hard drive is ~$200 and it will run faster than most NAS devices on the market at less than half the price. Using a one drive version for a poor-man’s PC might be a little under powered and you may want to look at the much more powerful version below that only costs $200 more.

Professional or gaming workstation: Dual-core with discrete graphics

If you ever wanted a cheap powerful workstation that you can take with you without having to carry it separately from the LCD monitor, this is the box for you. This larger box will fit and hide behind a 20″ or greater LCD display without being visible from the front and will only add 3.75″ of thickness to the entire LCD. It will take any MicroATX motherboard with enough cooling for a dual-core processor and dedicated PCI-Express graphics card.

With the 220W SPI220LE power supply, you’re limited to using 65W (Thermal Design Power) processors and graphics cards that pulls no more than 100W. Not to worry because you can get very powerful processors within the 65W power TDP such as the Intel E6750 2.66 GHz dual-core processor and the NVIDIA 8600GTS graphics adapter. We can load 3 hard drives, 4 half-height PCI cards, and use the on-board video card or we can load 1 hard drive and 1 full-height PCI-Express adapter. On the motherboard front, I look forward to reviewing NVIDIA’s 7150 integrated graphics chipset with an impressive features list and price.

Part Price*
Gigabyte G33 MicroATX with HDMI/DVI HDCP $126
Intel E2160 dual-core 1.8 GHz (very safe clocking at 2.4 GHz) $85
SPI220LE 220W 1U compact 80 Plus power supply $60
1 GB DDR2-667 (two 512MB DIMMs) $41
250 GB Maxtor SATA hard drive $63
Sub total (before monitor and tax if applicable) $375
22″ Acer DVI-D w/HDCP and D-SUB (*exposed* flat VESA) $234
Integrated graphics total (before tax if applicable) $609
NVIDIA 8600GTS $156
Dedicated graphics total (before tax if applicable) $765

* Includes shipping cost

Well there you have it, you have a powerful all-in-one workstation or LAN party machine. Get out your drill and saw and get ready for some fun!

how much power is behind that noise coming off George's unshielded equiment? I'm a ham too and hear the wipeout on certain frequencies every time I operate.
It would be interesting to measure exactly how much noise George is broadcasting.

Up the RAM and cost up to $800
nucrash 3rd Oct 2007
I wouldn't game with anything less than 2 GB. Not saying cutting edge, but many games that are unplayable on 1 GB with a weak proc come alive with 2 GB.


This also applies to the video card though. Other than that, not bad. I was pretty proud when I had a Quad core rig built for around $700 dollars.

Your board is an excellent choice. It can support pretty much any proc and video card. No SLI, but still, 1333 MHz Bus and Quad Core support... You can't fail on this model.

Heat will get interesting.
You just keep it under the 220W budget and you're fine on heat because there are 3 80mm fans. There are bigger capacity 1U PSUs though.

Cool Acrylic housing
dinas@... 4th Oct 2007
I think you can switch the hardboard & MDF with clear acrylic or Perspex material. The 4mm acrylic is tough enough for the base & surrounding enclosure. The price wouldn't be much different here with the wood. Then you can use the neon / LED fan to fancy the entire setup.

Built-in speakers and air flow.
burtoni 4th Oct 2007
George, in order to keep the external wires to a minimum why not build a pair of speakers into the sides? I'm sure you could bolt a cheap pair of laptop speakers onto it. Or you could extend the speaker output to a convenient spot so one could plug in a pair of headphones.

On another point, you have 3 fans designed into your micro-ATX case which appear that they would be blowing out the top of the case. Thats a good design point since the warm air will rise to there. However you may consider designing some air input vents that direct air over the highest heat generating components. You could do this simply by drilling an array of small holes into the side of the case nearest those components. This will likely improve your airflow as well.

Ian.
You'd have to expose the sides and make it wider than the display, but I like where you're going with this and I definitely think having built-in speakers is a good thing. What?s the point of having a beautify iMac all-in-one if you got clunky cables going to the speakers?

We could do a small car amplifier and car speakers internally. I guess they could face outwards unless we expose the top a little and face forward. The entire PC chassis would essentially become your speaker enclosure, but there?s some concern about shielding here because any kind of RF noise will get picked up by the speakers.

2 Watt speakers...
wesmantx05@... 7th Oct 2007
That is a good idea for getting some speakers in the deal, but 2 watt speakers always sound like they're under water. I have some 2 watts on my Sceptre 20.1in and they are horrible. Your on the right track on this I think. Built in speakers sounds like more of a plus if you were building this set-up on to the back of full blown HDTV with more like 35 watt speakers built in.

On that note, building something like this into a home entertainment "Media Center" sounds like an awesome idea! Or at least another article for George to tackle. Have you seen the prices on nice MC cases? They get real ridiculous real fast. The cost saved on this solution makes just as much sense as the portability of this system.

You don't need to by some over rated MC case if you building out of sight on the back of the TV, And you gain a LOT of building room. Who doesn't have a ton of space between there flat panel and the wall?

I would love to see this all planned out! I have been thinking about a Media Center in my living room, but I don't yet know if the PS3 will satisfy my requirements and then some. The idea of a computer built onto my TV running Windows Home Server, sound pretty cool to me too. Who doesn't want to play with Home Server, Dual booting Suse as well of course! (Pipe down Linux Junkies! Im one of you too!)

I don't normally write in on articles here, unless there is something I just feel strongly enough about. I also don't tend to go back and read replies to what I post for that matter. But I do make an effort to read almost all of the articles posted on this site! Great subject George!

Be careful with contrast ratios
burtoni 4th Oct 2007
Make sure you are comparing the right contrast ratio. That Samsung monitor still has a static contrast ratio the same as the Acer monitor that George is using (700:1 for both) at a fraction of the price ($119.99 vs $319.99). The Acer monitor doesn't quote a dynamic contrast ratio, presumably because it doesn't vary the power to the backlight. I still think the Acer monitor is the best value price-wise.

Seen it before!
peter.knapp@... 5th Oct 2007
That is more or less what they do with railway station plasmas (and now LCDs) in the UK. They take a commercial plasma (Fujitsus mostly), flatten a rubbish PC on the back without even opening the Plasma case and then they have a custom made tin rear made which covers the PC and PSU and provides the mounting points for the pole/wall mount. Unfortunately due to the fact these plasmas are already heavy and they are duplicating all the mounting hardware (they don't take the old rear off the plasmas, just clad another over it) they are incredibly heavy. One we were repairing was 110kg! These a phenomenal bits of kit to shift to maintain. Thankfully they are using LCD's with remote multi-head PC controllers now so they don't suffer from the same level of burn on and the mass failures due to the heat of the plasmas and the temperature high in the station on a sunny day..

Plasmas are power hogs

50" Plasmas take 500W of power and it's horribly inefficient. That's why so much heat is generated.

There are other sources for parts...
MidnightGeek 5th Oct 2007
I love the concept and have been working on a similar design for a client company's project. One of the best resources for "retail" parts I found is at http://www.logicsupply.com/ there are many low power options and motherboard designs for comparable prices. Most importantly for this project they have Cases and Power Supplies.
And they have the kiosk style LCD touchscreens With the computer in back. While I am not thumbing my nose at this project at all, I mention it far review material to see how they packaged the design for a retail target.
This project does well at opening minds to conceptual designs and show the true spirit of the hardware hacker is alive and well. In that spirit, I say don't stop at what you can buy in the local store. Hardware gems that will do what you want, The Way You Want, can sometimes be better served from online sources. Kudo's! I look forward to seeing how your design evolves.
I've seen them before and it's not what I'm looking for. I just bought a table saw (need it for home improvement anyways) and I have a much nicer design coming. Hope to finish it this weekend if I can ever figure out how to assemble the 100 pieces in this table saw.

EMI / RFI Radiation
jml5@... 8th Oct 2007
George -

PLEASE put some foil or at least copper screening around the inside of the box. Just because the computer appears to be working OK and you can't hear noise on the speaker lines doesn't mean you're running a clean system.

There's a reason that manufacturers put steel cases and foil wraps around computers. PC components put off a ton of RF, and the FCC frowns really bad at people who do it flagrantly.

I run ham radios, and people who casually dump RF without thinking about the consequences are a continual pain in the butt. If I remember right, the federal fines start at about $10,000 for anyone who does this on a regular basis. Not just for extended periods, but for just a second or third warning/offense. And there are hard-core civilian people who take pride in hunting down violators.

Please think about putting shielding around that monstrosity ASAP, and please also don't publish really poorly "designed" contraptions. If you're not willing to put the engineering into it, keep it to yourself. Publishing the design under the ZDNet banner gives you credibility, and could leave many unsuspecting system builders thinking that they're A-OK when they're not.
So when someone uses a clear glass case, they're going to get a $10K fine? C'mon, get serious. What about people who run PCs with the cover off, is that worth a $10K fine too?

FCC has requirements for motherboards, and electronic components, but I've never seen an FCC approved ATX chassis before. I can assure you that nothing in my room is being affected, nothing in my next room over is affected, and there is nothing in the next house being affected.

This is what you call a "MOD", and the FCC has better things to do than chase down a bunch of modders.
0 Votes

Yep, it's a mod.
jml5@... 10th Oct 2007
You're correct on all three counts - individual cases aren't approved, it is a "MOD" and the FCC does have better things to do.

Cases don't need to be approved as an individual device because without a power supply, motherboard, CPU, etc., they have no capacity to radiate RF. Unless a manufacturer or distributor is selling the complete assembled system or a kit of parts that can be bolted together into a system, certification isn't required. If the component parts (motherboard with CPU, powersupply, disk drive, etc.) are each individually certified, the assembly gets a pass as well.

I never said the FCC would chase down modders. I said that there are hard-nosed civilian radio operators who enjoy chasing down non-compliant systems. They use specially designed portable yagi and cube-quad antennas for direction finding. It's somewhere between a sport and an obsession. Once some form of noise-generating incidental radiator is located, they'll normally try to work with the owner/operator to resolve the problem (power companies have specific budget line items to cover these costs every year). If the owner/operator either can't or won't fix the issue, the civilians will kick the problem to the FCC and request assistance. At that point, the FCC has to open the investigation.

Any individual has the option to make a non-tested, non-compliant system. Just please be prepared to shut the system down if a licensed Ham operator starts pointing fingers.

So why are you comparining me to a radio pirate and warning me about $10K fines etc?
0 Votes

I never said radio pirate. That's a whole different animal in the realm of deliberate broadcast.

RF trash coming off of unshielded systems comes under the heading of "unintended radiators." If you would stop kicking yourself in the chin with knee-jerk responses, maybe you would understand that I'm trying to make three simple points:

1) Unshielded computer systems radiate RF noise. These systems are non-compliant with FCC guidelines for class B (residential) use systems.

2) If the system is not class B certified and interferes with ANY authorized radio spectrum users (broadcasters, commercial two-way radios, cordless phones, ham operators, Wifi, cellular, etc.), and someone files a complaint, the FCC will investigate and force the owner/operator to bring the system into compliance or shut it down permanently. Failure to comply carries significant (e.g. $10,000+) penalties.

3) You have both the privilege and responsibility of having a well-read and respected column published under a trusted banner. The privilege is being able to publish your opinions and findings to a mass audiance. The responsibility portion is doing everything in your power to publish truth (sometimes a nebulous concept in the PC ratings world), and information as complete as you can make it.

Not discussing RF noise radiation and trying to just make cool-looking toys is fine for the casual home modder. You need to do better. If you hold yourself out to be an expert or a professional, act like one.

As for me - I'm just another schmoe on the street as far as case building is concerned. I'm not a case modder, and don't have the need to be. I have a profession (I.S. Management) and a significant hobby interest in Ham radio and emergency communications. Nonetheless, our exchange has probably done more to bring the concept of RF shielding into this forum than anything published here in a long time, maybe forever. It's enough for me.

Reality check
burtoni 11th Oct 2007
FCC (and CRTC in Canada) only investigate reports of RFI if there is demonstratable evidence of interference with a device that is not designed to recieve in that band. I am also an amateur radio operator and I have been involved in some of these cases. Some guy on a fox hunt with a 30 dB gain yagi and a GaAs FET preamp connected to a broadband RX is going to pick up every clock radio in a 1 Km radius if he can get past the RFI from his vehicle. The FCC isn't interested in those guys.

Are you kidding me with the tons of RF statement. I work as a computer technician, and at any given time I can have 6-10 computers running with no covers.... I guess I must of radiated my brain cells by now.... or the FCC is really snoozing. I would be willing to bet with modern tecnology, the amount of RF coming off my unshielded computer is several times less than that of any TV, microwave, and cell phone. As far as screwing up your Ham radio... who cares...step into the 21st century, buy a computer... embrace technology....IM the other losers instead of trying to contact them with a radio.

Audio Cables
davids@... 27th Nov 2007
I haven't seen unshielded audio cables inside a computer case in quite some time. Every cable I've ever seen that went to the front panel was shielded.

In any event, they probably do pick up at least some noise. It's way out of the range of what you can hear, but it's probably measurable. Some cases *do* have noise suppression (usually in the form of toroids) on the audio in/out connectors on the front or top panel.

As a wish list for my next PC, I would want at least a DUO Core, and not just a dual core (like the Intel E6300 as a minimum). If there's something both cheaper and faster, then go for that (not sure about your choice of PROCs). Even with only one GB of RAM such a system rocks with speed. And also I would definitely require one of those all electronic hard drives (that people are waiting to come down in price); so that my PC would boot faster than any regular hard drive available (for the OS). I would also want a full TERABYTE hard drive (for the data); so that I would never run out of drive space; at least not any time soon.

Sincerely;


Mike Beaver CHt.
