There's plenty of room for an M.2 module, especially on the backside of the board which is how they're traditionally mounted on desktop ITX boards. https://i.imgur.com/dW0ynV7.png https://i.imgur.com/dW0ynV7.png They can also be mounted at an angle just like those SO-DIMM slots. The M.2 standard even supports 12mm, 16mm, and 30mm width modules in addition to the 22mm that seems to have become the norm. Apple could still be a dick by using a 12mm or 16mm card while still supporting the standard.
