I have been given an old computer case, it doesn't seem that big in comparison to my friends Dell XPS; which I think is massive. But I don't know if this empty shell of a tower is a full or mid sized case. I cannot find any information in or around the tower itself to indicate whether it is ATX, mid or full. Any help? If it helps at all, it was also previously determined that my da061/078l-am3 motherboard, will fit into an ATX mid sized case, hence my reason for question.
