I've been putting this computer together for the past 3 hours, and I forgot to buy prephiral cords. Not to mention my wrist strap's clip has fallen off twice when touching the motherboard, while I'm sitting on a carpet. Anyways, where can I buy the prepherial cords. I don't care where, even if it's wal mart, I just need to know where I can buy them. Oh, and I need one for my hard drive, and I need something to connect from my PSU to my dvd drive, hard drive, fans, and graphics card.
