Will any mobo have I/O connectors that match up with the slots on the back of any ATX case? I want to buy a case but I don't want to have to cut the back of the case to make connections with my USB, etc. connectors. I am not sure if I am explaining this properly, but what I basically want to know is if any mobo will work with any ATX case.
your mobo should come with its own specific shield plate, you remove the old one from a case (if upgrading mobo) or a blanking panel if the new case has one, then align the new plate as it lines up with new mobo and push it into place, there are retaining clips which can be tough to pop in though so dont think it doesn't fit
but yes, any Matx or Atx mobo will fit in any atx case,
dont forget your standoffs when you install mobo btw
ok, I believe you all, but my Mom bought a Gateway computer way back in 2000 and I put together an upgrade of the mobo, cpu, and ram. So, of course I used the Gateway case and I had to cut into a piece of the whole back panel because when I installed the metal piece, and I am not sure that I have all of this right, I couldn't make I/O connections. I am not sure if by the shield you mean the little 7X5 sheet of metal that comes with the mobo or you mean the metal piece that covers the entire back of the computer. My guess is that the shield is either not the whole back panel of the case or the Gateway case is just not meant for non proprietary mobos. Can someone confirm or help me understand?
The shield they are referring to in this case is the little sheet of metal with cutouts that matches the ports on your M/B. It's a 2000 Gateway so it is probably proprietary. The good news is that if you already have M/B, CPU and RAM all you'll need is a cheap $30 case, that usually has like a 300 watt p/s, and you should be able to make a functioning system from the pile of parts.
