quick question

Yes, read the specs of the mobo. They will say what form factor it is. The a7n8x and all other nforce2 boards are atx form factor.

Standard ATX is "full size"; Extended ATX is "super size" (so to speak). If a case or motherboard just says "ATX", then that means it's standard ATX. A microATX motherboard will fit inside an ATX case, too. ANYTHING will fit into an EATX case.
