i would suggest western digital hard drive, I've had bad experiences with the seagate and so have a few other people i know, i got a western digital and wa-la no more problems
p.s:
man i hate that! you americans can buy a kick ass system for $1200.00, if i bought all those parts in canada where i live the video cards alone is $1600.00 + 15% tax...damn next time i upgrade ill be getting that motherboard, cpu and video card thingy from newegg
