Your motherboard is the common ATX size.
Look for a case that supports a ATX size.
full/mid/mini tower does not mean much; there seems to be no standard.
Some mini tower cases will only fit M-ATX or ITX which are are smaller formats.
I might suggest the Antec 100. It is of good quality and inexpensive.http://www.newegg.com/Product/Product.aspx?Item=N82E16811129181
