Tachyon, that's one of my only complaints about this board as well. Tach is also correct about the -C revision as well. The CUSL2-C is only different by a few things; 1.) No onboard video/sound, 2.) No AGP 4x/PRO slot - only 4x, 3.) perhaps a different chipset in newer -C's. From what I've heard, the CUSL2 and CUSL2-C have identical benchmark scores.
My only real complaint about this board is the Vcore problem when extreme overclocking comes into play.
