HAF Stacker Overview
The HAF Stacker system currently comprises three components: the Stacker 935, the Stacker 915F, and the Stacker 915R. The Stacker 935 consists of a mid-tower case and the Stacker 915R. The mid-tower component is not available separately, but only as part of the Stacker 935.
While the mid-tower component can hold anything up to an E-ATX motherboard, the two 915 cases are mini-ITX only. The difference between the 915 models is that the 915R mounts the power supply at the rear, over the motherboard, while the 915F mounts the power supply at the front, under the single 5.25″ drive bay. Although the separately-purchased 915R has a front panel with a power button and USB ports, the version included with the 935 has no front panel.
The 915s are very large for mini-ITX cases. Compare the size of the 915F to Cooler Master’s own Elite 120 mini-ITX case:
The mid-tower component is a little smaller than the current Cooler Master HAF 932 case.
I’ll examine these cases in more detail in the next section
