To view this case mod, go here. Specs: QC 6600 Motherboard: ASUS P5N-t Deluxe Cooling: Watercooling, heatpipe. Memory: 2x1GB Crucial Balistix DDR2 800Mhz Video Card: NVidia 8800 GTS 640MB(PhysX®), 2xGTX260(SLI) Harddisk: 3xMaxtor 500GB RAID 5 config., 1x Samsung 1TB, 1xSeagate120GB CD/DVD Drive: Asus DVDRW multidrive with Light Scribe CRT/LCD Model: LG 20" (1680x1050)x2 Case: Custom case Sound Card: onboard PSU: CoolerMaster UCP1100W Software: Vista Home Premium Mods: Case moddifications: moved the PSU support closer to the mobo tray to allow mounting of a triple radiator on top; made the holes for radiator on top, fill port and wiring on mobo's tray, painted all black.The waterblocks for the 2 GTX260 are homemade, I used a small lathe as a router to fabricate those fron 8mm thick aluminium plates. Won't do it again, I swear! To be honest, I was working on this system for almost a year just to get some crappy ratings without any explanation. Thanks to those taking time to comment, much appreciated!I was running this system using a coolermaster real power520w. So much about power requirements! I switched to UCP 1100w just because I intend overclocking it. It tops at 505W on stock settings. The room temperature at the time of testing was about 36 Celsius degree and CPU idle at 37! Tested the graphic cards and those go as high as 76 Celsius for the 65nm versions and 65 for the 55nm. From my experience, overclocking 20% won't increase much the temps, maybe about 5 degree more.
