Update as of 9/11/11 - ditched water cooling and went for some peace and quiet
2600K @ 5 ghz on air (venomous x) - quiet push pull fan speeds
4 GB ripjaws @ 2133 Mhz 7-10-10-27
GTX 580 Lightning - stock for quiet
Kingston 128 gb SSD boot, 2 X 1tb caviar black storage (not RAID)
Win7 64
HX1000
24" Samsung 245t
Tt keyboard
Razer lachesis
(hope to switch to the 580 CUII for that awesomely quiet 3 slot cooler - but it's acting dead and needs some troubleshooting on the test bench....)
This is my idea of stability testing:
