Hey Guy's so I was asked to post my rig on the IRC by a few members so I decided to post one of the earlier pictures and then when I get home I will post the newest one showing the 4x 7950's hanging and going. I have 4 of these rigs stacked in a 4x square. These are just the standard plastic coated wire racks that you would have in a kids bedroom. I believe I spent about 15 dollars for a huge box of them?
This is the output currently with the 4x 7950 only issue is I am getting a dead gpu state on some of the GPU's after a while. Looking into why.

I will post the remaining pictures when I get home showing how I have the 4 cards suspended. The cool thing is about these cubes is you can actually turn the card sideways and then back straight and it will lock into the little individual square holes on the side so you don't even have to zip tie or support the cards. I then just have each power cable coming through the top and that helps support the other end. I only use the cheap little twist tie incase the card gets jiggled so it doesn't fall down.
Any questions or request for pictures let me know and I will gladly go into more detail.
