If you've read Jeff's review of the Fractal Design Define C, you already know that it's a fantastic ATX case that offers a lot of value for the money. (And if you haven't, go read it!) Some folks don't need all those extra expansion slots that ATX provides, though. For those people, Fractal Design has the Define Mini C. The new case strips off two expansion slots in its move to the MicroATX form factor, but is otherwise more-or-less unchanged from the full ATX version.
The shorter height (from 17.3" to 15.3") also loses you one of the fan mounts in the front of the case. Still, the Define Mini C will take two front fans and two top fans, as well as one in the rear and one on the bottom. Any of the mounts can accept 120-mm fans, while the top and front positions can also accept 140-mm spinners.
The case can take in up to two 3.5" and three 2.5" drives, and includes all of the features that builders expect from Fractal design cases, like sound-dampening foam and multiple cable management cutaways and grommets. As is usually the case with Fractal Design chassis, all of the intake fans are dust-filtered. Fractal Design says the Define Mini C should be available soon for $80 with a window, or $75 without.
