Still don't see a sound card. Did I miss it?
Built in on the mobo.
Just my 1/2 penny here...you're going for high end but you cut some corners where you wouldn't have to if you didn't go i7...I know 2 (so far) people here at work who have tried the i7 setups and both had to return the parts because of glitches...(none of it was off brand either)...the second guy spent 3 weeks trying to get it up and running until he gave up.
You could get higher internal clock speeds with a socket 775 and 95watt quad core processor...then you wouldn't have to deal with triple channel memory configurations (that aren't needed by the average home user)...and you wouldn't have to buy a 1000+ watt psu...
Step down to the socket 775 configuration with a higher clock speed processor and do 4 gigs of ram in dual channel configuration...you won't need more than that before you build a new system.
Ditch the Hanns-G monitor. I have several where I work and the quality stinks...even the Acers are better.
If you're going to do 64bit OS, Windows 7 is the way to go...Vista is just another Windows ME failure.
Forget the raid 0...no benefit to it in reality.
Looks like you got money to spare...save yourself a lot of headaches and stay away from the "bleeding edge" hardware that hasn't been on the market very long...it's depreciation value is higher than 1 generation back without the visible benefits you would expect.
