Overall, the build looks good, but may I make some suggestions?
For one, I think you're spending way more than you need to on the motherboard. Some of the higher-end motherboards, such as those based on the 680i chipset are overhyped. Yes, they have great potential, however they have to be in the right hands; you won't be breaking any world records unless you're a master overclocker such as those found at XtremeSystems. Furthermore, most people aren't going to be able to take their processors as far as some of those motherboards are built to go, something a lot cheaper gets the job done, and then some. ASUS's P5B
($180) is an excellent overclocker, one of the best ones around, and for a very reasonable price. Even the P5B-E
version ($151) would take your E6600 as far as its going to go.
You could also save some money on the memory, but it looks like its worth the price, so that's fine.

700W, 72Amps in this case, is way overkill even for that system. I recently recommended the Hiper 530W
($85) in a very similar build for a friend of mine (including 8800GTX).
Otherwise, looks like you did your homework on the hardware, they're all excellent parts. Nice case there too. If you do ever decide to get an aftermarket cooler, the
($54) is about as nice as it gets.
