Ares, thanks for the quick response. The power supply that comes with the case, is it good? Or should I pay a little extra for a better one?

Threw this together using redgarl's suggestions. It's a little more than I wanted to pay and I'd still need an OS.

broken wish list i cant see it

the antec 650 watt psu is a very good psu

yea, the antec is very good, and it is plenty for your system. if you want to shell out an extra 50 however, then get the combo with just the case, and buy a good 550-750 watt psu from ocz, corsair, seasonic, silversone, antec, or pc pc:

all of those are good

I think I'm going to go with ares's build. Since the PSU that comes with the case is good, I'll stick with it.

How is Windows 7 with backwards compatibility? I have a few games that didn't run that well on my current PC like World in Conflict and Company of Heroes and I'm wondering if I need to have a dual-boot with XP as an option.

Thanks for all the help so far.
