Hi All,

My first project build so I ask for your patience and understanding as I progress through this :)

This project started out of necessity, the way all the best projects do. Space is finite and I love to be efficient with it when possible.

My business deals with a fair amount of 3d rendering and animation so small, cool running render nodes are key to a smooth running project. We currently use the silverstone sugo sg05 . its a great case and works well for a cpu only render machine. we have from 6 to 10 of these in the office at any given time and when they are all going at full tilt they can kick out some heat and a fair bit of noise.


For years these have been good balance of power and size but it just wasn't enough for me. So the challenge I set myself was to try and make them smaller and more efficient.

I know some of you might be saying the best way to do this is to set up a blade server but they are expensive to setup and run. Plus in a small office environment they are noisy and can be unsightly.

So here is my solution that I hope will work. Enter stage the 3in1 Special.



This will be 3 thin itx computers in the same space I have one of my current Sugo05's. Made of Aluminium profiles and Perspex panels.



A hinged Perspex door to the front with 3 power switches and a 200mm fan will keep everything cool and give access to the 3 boards. Still debating if it should be clear Perspex or go for a solid colour.



Each motherboard tray will be attached to shelf runners so that the boards can be slid out for maintenance and cleaning.



Spacing's are crucial for this to work and even though clearance will be tight it should be adequate.



The base will have a aluminium plate but the top and side will be clear Perspex and the back will be completely open to allow the air from the fan to pass right through.


Parts List so far:

Mainboard: Asus H81T Motherboard (Intel H81, SO-DIMM DDR3, S-ATA 600, Mini ITX, HDMI, DVI-I, e-SATA, USB 3.0, Network iControl, Socket 1150) (works with an external brick or internal PSU, this is the only reason this build will work)

Memory: Crucial 16GB (2x 8GB) DDR3 1600 MT/s CL11 SODIMM 204 Pin 1.35V/1.5V

CPU: Intel Core i7 4790 (non K version) with stock cooler.

HDD: Crucial CT120M500SSD3 120GB M500 mSATA 6Gb/s

PSU: 150W Genuine Original ASUS 19V 7.9A AC adapter (external power brick)


The parts may change down the line, my first priority is to see if the case can be built to spec. When I've got that sorted I'll order the rest. This whole project I want to do on as tight a budget as possible but still with reasonable parts.
The aluminium profiles are on there way and hopefully will be easy to work with as I've never used them before. They seem to very robust and multi functional so fingers crossed.
That's it for now, I'll post next when I have the profiles and I can start to make some real progress.

A colleague of mine set up a case like this for bitcoin mining rigs. He had five motherboards stacked on top of each other in a case made from a modified set of metal shelving units. The beauty of it was that the shelving units were themselves stackable so he could have added more levels for motherboards if he'd wanted. Make sure you have a large fan at the top of the case, and if the motherboards aren't being directly bolted to the frame, make sure there are lots of perforations in the plates that the motherboards sit on to allow for rising heat to escape.
Good luck with your project!
 
I agree with the above posters, turning the whole thing 90 degrees on its side makes a lot more sense to me. Aside from that, it looks extremely neat and tidy!
 
Hi folks, thanks for the comments and feedback. It hadnt actually occured to me to stick it all vertical and now that you say it, it makes perfect sense. Unfortunately there isnt the space to stack them that way in its current configuration. These need to fit into our current cubby hole shelves which are only a few mm wider than the outer dims as is.

Luckily though if we dont need use the shelves in the future the whole thing can stack as is or be rotated 90degrees and still stack with a simple joining bolt. The pleasure of working with these aluminium profiles that nothing is permenant. everything is bolted or screwed so easily reconfigured down the line.

With regards to the cooling, i would have thought the 200mm fan will be enough to push all that warm air out the back. I might look into a perforated panel for the top just to help.

I'll be updateding later this week when i start work on the profiles.
 
3in1 Special Update 1

The aluminium profile parts have arrived and I can finally start to play around with everything. Reminds me a bit of mechano kits as a kid :) love it!

I got the length pre-cut to save time as cutting this stuff accurately can be a nightmare. I'm pleasantly surprised they are all the right length with nice clean ends. Much lighter then I thought they'd be as well.



All the cross sections, self tapping screws, hinges for the door and end caps for keeping everything neat.

First thing I try of course is to screw the 'self tapping screws' into place. I didn't get very far. I don't know if the crews are too big or what but it takes a good effort to just get them in this far.



All I did was grind out the top of the crews trying to achieve this.

So after purchasing a proper m4 tap drill bits I proceeded to tap every profile.


Jobs a good un!



Success! A little looser then a would have liked but still secure when tighten completely



All tapped and ready for construction.



What one of the sides will look like.

Its a real pleasure working with this stuff and has me thinking I might build a computer desk out of this stuff next. This is the 20x20mm profile but they go up to 80mm. Strong and light weight, you could easily setup the structure of a desk with room for a computer to be built into it. Off topic though, that'll hopefully be my next build, always wanted to move my computer into a all in one desk.

This is all I've had time for this week I'm away this weekend so I'll pick up where I left off next week. Sorry if this is little boring at this stage, I'm looking forward to actually getting the kit installed once the case is finished.
 
Looking good so far, and it is perfect material for making computer desks from (my Dad made a couple in his workshop for an animation studio using this material).
