Wow at 13.8" tall and deep with 6.9" in width, this a nice look little case for a Mico ATX. The rear 80mm is a bummer and can't be certain if the extra holes are for a 120mm but there may be room to mod one in there.

Pics on the'egg show extra set of holes for 120mm rear fan.

yes the max rear fan is 92mm, not enough room to fit both a 120mm fan and mobo w/std rear I/O plate in a 6.9" wide case. Don't think it's a big deal though, for the typical build you'd put in one of these a low RPM 80 to 92 mm fan plus the front fan should suffice, maybe even enough airflow without both of those unless using a high power video card or significant overclocking.
