Black Pearl is overpriced and has SATA drive issues... If you want asus go with P5K-deluxe or P5K-e
Q600 is nice
I would get better ram than Hynix... OCZ or Crucial are popular and nice, if you are running 64bit OS id look at 4gb instead of 2gb
dont get MSI for 8800GTS look into BFG, XfX or eVGA. Also the new 8800GT comes out in a few weeks that COULD well be a GTS killer and cheaper.
The rest is good but id turf the ultra-x crap and get a G15 or 11... the G15 just went through a revision to make it a little sleeker
WOAH hangon i though SangYang made cars... Get a decent PSU... Corsair, OCZ, Antec or PCPC
