I just got the Rosewill RP550, the highest end model they offer, and it runs great. 34A on 12V
The OCZ Platinum Revs 2 are great overclocking ram. If not, the Gold Series would be just fine.
That motherboard doesn't look that great. The DFI Lan Party UT nF4-D can be purchased for $112 on Monarch Computer.
Don't buy the retail Audigy ZS. Get the OEM and save urself about $20.
Don't forget Arctic Silver 5 and maybe a cooler for your video card.
