I have an M-ATX motherboard but I like ATX cases. I am thinking of getting another case. The case I like is ATX only. Couldnt I just drill and tap new holes to fit the M-ATX motherboard instead of buying a case made for M-ATX?
Micro atx boards should easily go into any standard atx case without issue. A simple lack of one row of mounts needed due to a lack of height is the main difference between the micro and a full size board.
