The case is good.
The mobo might as well be a P5N32-E SLI Plus, save some cash.
Video cards: either 8800 GTX or 8800GT, depending on how much you can spend. The 8800GT is better value, but the GTX will be better at high resolutions and a bit faster and quieter and cooler and it will support triple SLI later if you get a 780i mobo and want to add a 3rd card.
PSU: for that money I'd get a PC Power & Cooling Silencer 750W Quad.
RAM/Cooler/fan: if you are planning to overclock the CPU a lot then you made great choices. If not, get 2x2GB RAM and (maybe) a cheaper cooler/fan combo - for example a Scythe Ninja and use it with its stock fan, or an Arctic Cooling Freezer 7, or don't buy a cooler at all.
Disk: WD7500AAKS is a bit better priced per GB and faster.
DVD - don't know. I haven't bought any Sony product since the rootkit garbage they did in 2005. I'd buy a Samsung SH-203B or PX-810SA or LG GSA-H62N or similar. Even if you like Sony, dump the IDE thing and get a SATA equivalent.
X-Fi: if you intend to use Vista then you're better off with an Auzentech card.
