My old pc fried, and I was given this one to tide me over. I'd like to supplement this one with my old hardware. So now I'm looking for a new tower. This one is entirely too small... my problem is I don't know which motherboard i have, and whether or not it's compatible for the towers that I'm looking at. for instance, is my motherboard compatible with Amazon.com: APEX PC-319 ATX Mid Tower SL 300W 4 2 (4) Bays USB Audio 2*FAN C2D System Cabinet - Black: Electronics ? I'd appreciate any help you can give me, thanks.
