I might overclock this system a little bit, but I don't want to buy additional cooling components so it will be very little. Any suggestions or advice would be great. In particular, I am a little edgy with the PSU. I'm not sure if I need a 650 W or if I could get by on a smaller one. Also the PSU I currently picked out says it only has > 70% efficiency, this seems low to me. Thanks for your help everyone!
Hey, well i recomend going for whatever you are comfortable spending as far a PSU but as long as its a good brand, (that one is pretty extreme but good) you could go for a 550-600 range for that system, you shouldnt encounter and problems. Watch out for the CPU HS and the cases layout, i have heard of people not being able to fit thier HS in under the supports for the side hole.
I greatly recomend OCing, i take it you have OCed before, but instead of a e6600 i recomend the cheapest 4mb cache C2D you can get, e4320 or somthing? then just overclock to a nice 3ghz, on fairly standard HS. That case has great airflow, ive built with one before.
As far as efficiency goes, 70ish to 85% is very acceptable, i dont recomend anything under 80 personally as they are quiet and cooler.
Also could you please add it's general purpose so we know what load its going to get, eg gaming.
