I've done a bit of research and come to these parts: they won't be exactly these, as I might SLi 8800 GTs and get 2x the 2x2G memory kits and get a different but similar mob to support SLi and/or other mods. Anyway, this is what I've got. Low cost too, definitely under $1200 including a case I have yet to decide on (any suggestions? <$100) and an optical drive.
