Or if you want a really high end psu
Newegg.com - PC Power & Cooling Silencer 470 ATX ATX12V Ver 2.2 470W Power Supply 100 - 240 V UL, cUL, CE, CB, RoHS - Power Supplies
Very nice Case. $10 less than the one I was considering
Newegg.com - Rosewill R5604-TBK 0.8mm SECC Screw-less Dual 120mm Fans ATX Mid Tower Computer Case - Computer Cases
cool
For the PSU, I was told to be careful with that one and not skimp here, specially since I'm gonna go SLI with 2x 9600GT
So I found this one:
Newegg.com - PC Power & Cooling S610EPS EPS12V 610W Continuous @ 40°C Power Supply 100 - 240 V UL, cUL, CE, CB, TUV - Power Supplies
Although the 2nd PSU (the first one seems too crappy) you linked, looks technically good it's ALSO way less expensive than mine, ...
BUT WILL IT do the job that my rig will require?
