I recently assembled a new system with the Gigabyte UD3P.
When I was installing it, I left the grounding arms on the i/o shield flipped up, as I didn't want to short the motherboard. I have been using wireless, but am thinking about connecting it to ethernet cable. Should the grounding arms on the i/o shield be touching the top of the ethernet ports on the inside? If they are not, will it kill my motherboard? If they are, is that bad?
