Before even trying to make a writeup, what do you plan to do with this computer? Do you game? How much, occassional or hardcore? What else do you do, just web browsing or things like constant hardcore encoding/rendering?
I'm building a rig for like 2 grand myself, going with...
DFI NF4 Ultra
San Diego 3700+
2x1GB crucial value
6800GT or perhaps 7800
Audigy 2ZS
Maxtor DM10 300GB
NEC 3500A
PCP&C 510 ATX PSU
Some things there you may not need, specificly the 2 gigs of ram unless you have a reason, or the Audigy 2ZS if you just use crappy speakers/headphones.
So there's an idea of what I'm getting, still undecided on case and watercooling setup.
