It will only work if you have a micro-ATX form factor board, which measures 9.6' x 9.6'. Most SSF or XPC boxes have changed over the years giving better power and more space. A M-ATX board will fit in any standard ATX case as well, however when moving to a 'mini-pc' cast you may be forced to leave behind a floppy dive, only fit one opti decvice, and in my own experince (just built my fist xpc) have to find a cpu cooler that clears the psu in terms of clearance.
