According to iFixit, there's a nice big air gap around the SSD card. They were able to get a regular SSD (9mm) to fit in there but the bottom cover just barely wouldn't close.
It'll be interesting to see if one of the slimmer models (like the 7mm Crucial M4) fits in there... if so, all you need is an adapter cable.
