I confess....what I failed to mention was that the back plate that came with the board has those little metal parts that are cut to stick out against the individual ports holes of the case...i.e. mouse, keyboard, etc. Yet, the mobo already has one portion of metal sticking out from the metal around one of the usb ports. What I was really concerned about...was if it had something to do with grounding. Must again confess, I really never knew the answer as to why those metal parts of the back plates are sticking out.
