k, i'm surpised you got that for $1300 american i'm guessing. anyway, looks good. That RAM looks good but extremly cheap, donno why. Um don't know anything about new intel stuff, so down to sound. The creative x-fi xtreme music is good and should be just over 100 us.
EDIT: don't get a raptor, get a WD se16 250gig, its cheaper and bigger.
DDR2 800 is has a mail-in rebate for 40 bucks, thats why is sounds cheap. System looks good to me. If you are gonna get a 10,000 rpm hard drive I would get the smallest one possible and put only your main programs and software on it. Then get two 160gig drives and put em in a raid setup.
