After looking at some of the builds on this site and getting advice from a friend with more experience than I, this is the build I'm looking at. Again, ~$1000 budget, focus on gaming, ease of assembly, and room for upgrades.
The biggest thing I'm trying to figure out is what MoBo to buy. My friend recommended getting a P67 chipset mother board, socket 1155. From what I've read, this is more of a gaming board than the Z68 (no onboard graphics).

$94.99 - Saw this on another build here and thought it looked good. My friend told me that >650W should be enough for one GPU and a few HDDs
