Hello guys, I've had a dell pc for a while now and recently got told that there is a Asus P5N-MX Motherboard in it because the original board broke like a year ago, Anyway....... The Asus P5N-MX motherboard that is in there now needs replacing as its packed up, I cant seem to find this motherboard anywhere as its been discontinued, Does anybody know where I can get 1? Or if there is an alternative motherboard that will fit into the box I have? Many hanks in advance....... John.
