4. Do I need a 450W power supply? I just threw it in there. I understand video cards use a lot of power, but I only plan to have one video card. I could get a cheapo case and power supply instead.

I bow to your collective wisdom and experience.
Looks good, but I would recommend using Corsair Value RAM instead of XMS (as long as it is cheaper) as it offers not much latency/speed difference and is generally a bit less expensive. (Run memtest86 once you get it, but it's worked great in all 7 or so computers I've built with it.)
Also, instead of the ASUS PSU, get a Coolermaster RS 450 ALCY:

I've been running one for a year powering a Geforce 6800 GT, 3 HDDs, and a Pentium dual core CPU (an overly power hungry CPU), and the PSU runs quietly and efficiently. It's also got active power factor correction and runs at a higher efficiency than most PSUs.

Anyway, just $0.02
