  • A good quality case with lots of storage space and good acoustic properties.
  • Rubber grommets come off easily, easily fixed, but wasn't a problem on the Define R4.

Sound dampening, dust filters and non obtrusive looks were reasons for picking this.

SOLID! I got it for $20, and put a window and shroud in the thing, and it is one sexy case.

Since the computer will be right beside me, I really need to make sure it doesn't make too much noise.

One thing to be aware of is if you are going to mount a single rad on the rear, it will be in the way of the side for either the sound damping foam or any cooling fan to be mounted there.

The optical driver bay's screws are very hard to remove. Guess this is only applies to particular unit.

This case is the easiest mATX case I've ever built in. Plenty of accessories included and many config options for this small of a case. The only issue I have with this case and motherboard combo, is the missalignment of the CPU cooler mount access in the rear of the mobo tray. I dont know if MSI made this board with the socket a smidge lower than other boards on the market or if the problem was with Fractal not accommodating a variety of socket placements. 4 solid stars.

Great case. Hard to believe it's a micro ATX case when you build in it. Plenty of room and options. Cable management great. good airflow. Top notch quality. The case is heavy thick metal. Doors are heavy and solid. Very impressed.

Excellent build quality and design. I love the front panel look, cable management is a breeze, and the airflow is to die for.

But. Could use a revision with 2.5" drive slots behind the mobo, and it is quite large for a Mini ATX chassis.

Sleek and minimalistic case with noise reducing padding. It comes with a standard 6 bay 2.5 or 3.5" hard drive bays, enough for a decent NAS. The 3 fan controller is helpful to have full manual control over the included silent fans - I've turned mine to the lowest setting and the CPU temperatures are still very cool. Cable management is not a problem with spacious cavities for a uATX build. 3 very minor issues with this case, using the slot on the back for the fan controller is difficult as the screw to remove is hard to access unless the back fan is removed; the thumb screws for the side panels were a little tight and did not seem to remove easily; the led for power at the front is very bright - would be much better if dimmer. Overall, ignoring the minor faults, is has been best case I've used in a build and would strongly recommend to others.
