Joining together two titans among Cooler Master case series, HAF Stacker takes the essence of the widely popular High Air Flow and Stacker series and elevates them to new heights as a single, cohesive line. The large drive storage and interior space of the Stacker series meets the Water and Air cooling design of the HAF series. The result is the first modular and expandable full tower with smaller companion cases that all stack together seamlessly.

HAF Stacker - the first expandable system that allows externally modular upgrades. The HAF 915F/R is a Mini-ITX case with removable top and bottom for additional stacking. Support of up to 360mm radiators in the stacking mode makes HAF 915F/R a powerful liquid cooling solution for system building enthusiasts.
