? whats up with your info man, DDR400 = PC3200
1. I take it you're going to be overclocking, then you'll want g.skill's pretty much, unless you can get an awesome pair of OCZ EL 3200 Platinum Rev2.0's.
2. I think the Neo Power is their premium line of PSU's, the Truepower 2.0 is just a cheaper line, although if the neo 480 is more expensive, i'd get the Truepower 550W
3. the rest looks good, have you thought about a Plextor DVD Drive instead of the NEC you have listed? Plextor have a nice SATA drive, although its *quite* pricey.
have you got speakers already? or don't you need them?
