There's room for two 60mm fans, a side mount for a 2.5" HDD/SDD and under the ODD tray there's a mount for a 3.5" or 2.5" HDD/SDD. If using a board with the HSF, there does not appear to be room for a 3.5" HDD but a 2.5" HDD or SDD will fit with a low-profile HSF. In the LCD/VFD window, there's room for an LCD/VFD module and a small round window for an IR receiver. There a screw holes to mount an LCD/VFD module but it's not clear what off-the-shelf module would fit. I am going to try the nMediaPC OEM LCD which is readily available.
First impressions are that it's a beautiful case. I can see why everyone raves about the m10. There's enough room in here to build a substantial HTPC while at the same time the footprint of the case is very small. It always surprises me how small these cases are when you see them in person.
