Closer Look: HAF Stacker Mid-Tower

The mid-tower component of the Cooler Master Stacker HAF 935 is a typical mid-tower case. There are three external 5.25″ bays, 8 slots, and a very large smoked Plexiglas window in the left side panel.

Inside the case are two 3-bay cages for 3.5″ or 2.5″ devices. These can be removed, but doing so requires removing six screws: four screws secure each cage to the chassis, with two additional screws connecting the inside edge of the cage to the rest of the case. The motherboard area has a  large cutout for access to a CPU cooler backing plate, and two pre-installed standoffs with chamfers help position the motherboard during installation. There are numerous grommeted cable pass-throughs and tie-down points. The 120mm exhaust fan is the only fan included.

The power supply area has four slightly-elevated rubber supports and a bracing ridge to help keep the power supply in place.

There’s a single SSD mount on the back of the motherboard tray, just below the CPU cooler backplate cutout.

I measured just over 5/8″ space between the back of the motherboard tray and the side of the case. However, embossed areas such as the one to the left of the ruler provide addition clearance for bundles of cables.

At the rear of the case we can see three grommeted holes for water cooling hoses, the exhaust fan and I/O panel cutout, the 8 card slots– with a handy “9th slot” for fan controllers, light switches, and the like– and the power supply opening.

With the front panel (and upper drive cage) removed, we have a straight shot into the case interior. If you remove both drive cages, a 240mm radiator will fit at the lower front of the case.

The front panel has a power switch, microphone and headphone jacks, two USB 2.0 ports, and two USB 3.0 ports. Disappointingly, there is no reset switch or drive activity light.
