a case is a case.. its not like its gonna go away or something lol so i try to save money and be smart, it really doesnt matter what kind you have, and my motherboard is good, how would you know if it isnt anyways, my harddrive was the same, and the xt isnt TOO much different from the pro besides its a bit faster, also you never mentioned the speed of your ram in the first post about your computer so if it was 2700 then it could have been the same also
