I have an old Gateway (Model # MFATXPNT ESX E4000) which I'd like to upgrade several components starting with the motherboard. [ I should mention that this is my first time rebuilding a pc, so I'm starting out with a basic knowledge of hardware. ]
Anyway, I would like to replace the existing motherboard with an ATX or mATX, but I'm having difficulty determining if those form factors will be compatible with the case. I think the existing MB is an mATX because there are only 4 exp. slots, but how can I be sure?
I'd be wary. I've done similar kinds of upgrades, and it's always a pain trying to work around the original hardware. For instance, getting all the unmarked I/O plugs to play with a new mobo can be a pain. With your level of upgrading, I'd spend a couple more bucks on a case and psu and boom, you've gotta a new build (minus the OS). You could get the rest of the parts you need for probably like $80 if you shop around and steal the optical drive from your old machine.
