you picked a lot of top quality parts, however I found a few things you could save money on.
Memory, while the HZ's are really good, they're not much, if any better then these
Newegg.com - Crucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Retail
and the Ballistix are a lot cheaper.
Video card, While the GTS 320 is a great video card, since the 8800GT came out I suggest waiting till they come back in stock and order one of those, or wait for the new Ati equivalent.
Also the only AMd processor worth somewhat getting is the 5000+ Black Edition, as it's unlocked multiplier comes in great handy, other than that, go Intel, even with cheap processor's the E2160 is tough to beat.
PS: I love and am going to get that monitor soon.
