I just purchased a Antec p-180 case and an asus a8n sli premium motherboard...what I would like to know is where do I plug in the second hdd led plug???? and do I really have to??? This is my enaugural birth by fire in trying to put a system together...I finally figured out that I had to rip my 8 pin connector in half from my newly aquired enermax 620 power supply to fit it to 12v 4-pin on the mobo...please help.
