On my sli bridge (asus) there is a little, i guess puncture, but it is not fully punctured... get it? anyway it doesnt seem to be a problem. But i have 2 of the bridges... and before i got the second one, i realized there was a little black spec on it. I kinda scratched it off cause i thought it was dirt heh... then when i got my second one... there was a little black spot on that too. Any ideas why that is there?
