One of three rigs:
-AMD Sempron 140 CPU
-G-Skill 2GB DDR3 RAM
-Gigabyte 990FX-UD3 (great motherboard, cheap and has good PCI-E layout)
-Western Digital 80GB Hard Drive (WD800JD)
-AMD Radeon HD 5970s (the new OEM ones that came out, solid overclockers)
-Cougar GX-1050 (great efficiency and rail design, only has 6 PCI-E cables though)
I have 3 Scythe Slipstream 120mm 1900RPM fans blowing cold air down on the GPU chips, they make a huge difference in VRM temps so the cards don't throttle down. These fans are quite amazing, great price, great CFM, and acceptable dBA (nowhere near my 5970s @ 70% fan speed). I also have a Honeywell table fan circulating the air. The whole rig and cooling solution only uses 700 watts so mining is still profitable, for long-term mining I focused on energy efficiency first and foremost (even over cooling or hash rate). This rig does 1520MH/sec (380 MH/sec for each GPU core). It sure doesn't look pretty but it gets the job done, the mobo is laying on some computer case sides from junked computers I found by the dumpster
