Thanks guys.
I think that I have the SATA connectors. The guy that diagnosed the mobo was showing me the guts & he mentioned SATA (I think) little "L" shaped plugs on the hard drive compared to a longer strip of pins kinda connector on another computer, right? Pretty tech savvy, aren't I?...

I don't know about the GPU though being PCI-Exp. Can I tell by looking if you tell me what to look for?
I'll have to buy another Windows lic even if I keep everything the same except mobo? Dang.
I'll do a search on here for the best route to go in building a box & where to buy. I've heard of Newegg for electronics.
Should I just get a basic Dell like this Inspiron 560 for $270 or is Dell a dog? And if I go with a new comp can I transfer my info from my old HD easily?
