The standoff mounting points in a PC case are done in a standard pattern and spacing. The Z77 EX 4 uses standard ATX mounting hole points, even if it's size is not quite ATX size. Just be sure that the number of standoffs on your case now are accounted for with holes in the new board, and remove any that are not used by the new board.
