If i transfer the guts from a Dell Optiplex 780 SFF into a BTX case that dell didn't make, will it fit? I am aware that I would have to find the diagram for connecting the power button and usb jacks, etc, but that shouldn't be too hard. Basically I want to get a bigger case so I can fit more hard drives in it, and possibly throw an actual graphics card. So can I get an aftermarket case, or should I try to track down a case for the tower sized 780?
