This little baby is four GTX295 in a custom case made by Protocase
There's a PDF with more pictures here
The custom case cost $343 for one case, dropping to $204 each for an order of 10

Here's a setup made using the Manifold PDF with slight different parts, by a guy in Nvidia forum
* Enermax Galaxy 1250W PSU
* Intel Core i7 920 (2.67 GHz)
* 4x EVGA GTX 295 cards (the new single PCB variety)
* Manifold Custom Case Rev 2 from Protocase.com
* 3x Thermaltake A2018 120mm fans (blue LED and various speed control options)
* Rosewill RFT-120 120mm fan filter
* Patriot Viper 12 GB RAM PC-10666 kit (6x 2GB modules)
* Intel X25-M (G1) 80 GB Solid State Disk
* Asus P6T7 WS Supercomputer motherboard
* Running Scientific Linux 5.3 (this is a RHEL 5.3 rebuild, like Centos) and CUDA 2.3 driver
Total cost is $3800, a little over $2k is for all the graphics cards
Notice that this little baby run ULTRA-HOT at 100% GPU speed so its not a good idea to make one yourself at home
