A Little Help Here?

[1967mustangman]

I have an old computer that I want to give to my sister (for an e-mail and websufing computer). It is and old IBM case and I have heard it called PIZZA BOX. Cna anybody tell me what it might be and what form factor motherboard it might take?

if it has PS/2 for mouse and keyboard then it is ATX, if it has AT connection for keyboard and serial connection for mouse...then it is AT

Well what is the MT(Machine Type) number on it. Most of the old IBM PC series used a riser card making using them nearly impossible.

Yeah it had a riser card and I had to pull the whole blasted thing out to get at the hard drive! I even had to remove the power supply to get at the stupid hardrive carriage. Ohh how I hate desktops!
