Okay, this is what I am looking for. I need a replacement mainboard for my computer. The computer is a Power Computing Power Tower Pro. Any speed of Power Tower Pro mainboard will work.... IF.... It either has the serial number (found on the computer case) of greater than 1482xxx or has a production date (also found on the back of the case) of Aug-1997. I am willing to buy the entire computer if you have what is stated above. Thank you.
