What is a ground pin? The instructions on my chassis (antec p180) say that I should connect the RESET SW to the RST connector on the mobo (nForce 680i SLI), and that the white wire for each connector should be on the ground pin. I don't know what that means, the ground pin? Also, the POWER LED is 3-pin but the slot on my mobo is 2-pin. How do I remove the pin from position 3 and put it into position 2, just pull it out? Thanks!
