This is an open air system I have been developing for awhile and its finally to the point where I am ready to share it with the community.
The rig cases are made from a wire shelving system you can buy from walmart. I build the bases for the motherboard out of 2 x 4s. Parts of the wire frames are stapled to the wood base for stability.
Cooling is provided by the NY Winter (actually very mild this year), I built an awning over the outside of the window and have two layers of screen to prevent snow/rain from getting in with a window fan in the middle to blow in the cool air, the big fan on the side blows the fan a crossed the back of the rigs.
Specs:
3 x MSI 890FXA-GD70 Motherboards
3 x AMD Sempron 2.7 Ghz single core CPU
3 x Crucial BallistiX 2GB DDR3 Ram Memory
3 x Corsair 1000watt 80 Plus PSU
3 x Sata HDD
6 x PCIe16 Extenders (3 Powered w/Molex connector)
3 x PCIe1>16 Extenders
15 x Radeon HD 5870
Windows 7 x64 w/ CCC 11.9 SDK 2.5 CGMINER 2.2.6
Clocks 950/180 - Fans @ 50% - Average Temp 58.5c
(stats example from one of the rigs)
Total Hashrate 6500 mhash/sec
