actually i spoke with one of my sellers who is testing out builds for a Conroe system and he told me specifially that the NeoH PSU have compatibility problems with the new conroe system. soo im going to a;
PSU: 550W E-Power Tiger EP-550P5-T1 ATX12V v2 and EPS12V 24pin/20pin Power Supply SATA PCIe SLI Ready $82.80
If your gonna pay 82 bucks for a PSU, might as well pay a bit more and get an Antec TruePower. Probably the best 550W PSU for that price range. Everything else looks good to me. E6600 is recommended, but like others said, if your on a budget, then 6400 should be fine.
