So right now I have a Dell GX260, it has a pentium 2ghz and agp, I was looking at upgrading the mobo to one that has either am2 or a 939 (to get an opteron 1.8ghz dual core, i think 165...) and pci-e (to do some gx10 gaming later on). is it as easy as taking the old mobo out and dropping a new one in or does dell have some weird case that wont allow this (the case is small desktop). Or i suppose I could just get a case and take out all the Dell stuff (hd, ram, cdrom, power, ) and drop it in the new case...Anyway thanks for the help
