Cooler Master HAF Stacker 935 Case Review

The inside of the HAF 925 is reminiscent to the Cooler Master Scout 2.  There is a large opening in the motherboard tray for heatsink access along with rubber grommets covering the cable paths.  Drives are located along the front with the external bays facing out while the 3.5” drive bays are rotated for easy access.

Drive trays are a tool-less design that slides apart allowing the drive to be positioned in the tray and locked in place using the guide pins.  2.5” drives are still screwed down from the bottom.

Unlike the Scout 2 you will only find six internal drive bays with several more behind the motherboard tray for smaller SSDs.  The drive racks are removable giving you room for long video cards and miscellaneous watercooling gear.

The HAF 915 comes in a similar configuration and while it is setup to support a Mini-ITX system build we get the impression that was an afterthought given the lack of a dedicated motherboard tray, position of the power supply and lack of secondary power button.

A single external 5.25” drive bay is located in the front along with a slim slot above that so you can transfer the front panel connections from the HAF 925 to the 915.

You will find a single fan located at the front of the 915 tasked with keeping the hard drive bay cool and accounts for the second included fan. 

A big part of making the HAF Stacker work is the interaction of the two modules.  The top of the HAF 925 is configured to support a multitude of radiator configurations and fans.  Of course if you stack the 915 on top this area will primarily be a cable and hose route to the chassis above. 

The bottom of the 915 features a single grommet opening and four smaller squares.  Ideally the only thing passing from one case to another is SATA cables and cooling hoses but you cannot deny that the top of the 925 doesn’t match the bottom of the 915.

Likewise the bottom of the 925 is following a typical cooler master pattern with a fan filter over the PSU opening followed by two openings for cables and wires.  The openings here are considerably smaller which is likely not a limitation of space but rather size of rubber grommet.
