yeah, I'm getting my video card from EVGA and PSU from XFX. they do green color schemes pretty well. I'll look into their mobo's as well. and I'd love a board with green slots and green heatsinks on the north/south bridge's. I'm not too concerned with the base board, but green or black would be nice.
EDIT: I looked into it, and XFX makes some black and green boards that would be sexy as hell, but I can't find any AMD boards that'll work with the CPU I've got picked out (Phenom II X4 965 Black Edition Deneb 3.4GHz 125W). I've always used AMD, so could someone give me an idea of what that compares to for an Intel chip in case I decide to go for Intel on this one just for the color?
