get the asus a8ne if youre not gonna go sli. for video card, get the x1900xt, the cheapest one you can find, theyre all the same, and i doubt the retail packages are interesting, so no problem with going oem. for the psu, get a fortron 500w psu for about 90 on newegg, it has sleeved cables, and is one of the most respected psu brands. for ram, get the gskill 2 gb kit on newegg for 194, or that ocz one, theyll both be fine... as for the case, look at the nzxt lexa, good cooling and relatively quiet.
