i have a regular case, i cant explain it, but it is an older case. im assuming that mobo that is sitting in it right now is a regular ATX. i measured the mobo and it is roughly 11.5 by 8.5 inches or so. now, the one i ordered is this: http://www.newegg.com/Product/Produ...-_-Motherboards+-+Intel-_-GIGABYTE-_-13128049 it says, uATX, im assuming it means micro ATX (which i verified off of the gigabyte website). how i can i find out if it will fit in my case?? are they interchangable??? also, will the mATX mobo be compatible with a regular power supply (i ordered one too!)??
