HAF Stacker Series

Chino, California – October 15th, 2013 - Cooler Master, a leading creator, innovator and manufacturer of desktop components and more, today officially makes available to the world the first stackable computer case series, the HAF Stacker Series. Launching with three connectable and stackable models, HAF 915F, HAF 915R, and HAF 935.

Series Convergence

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.

Expandability and Modularity

Available in three distinct models, the HAF Stacker series features a full tower HAF 935 configuration consisting of the HAF 915R and HAF 925, M-ITX HAF 915R, and M-ITX HAF 915F.

Each base configuration offers unique features and benefits that stand out on their own merit while being stackable with other models in the series for expanded functionality.

This is all made possible by a CM patent pending rail system that was inspired by a military picatinny rail to enable the attachment and removal of each stackable piece in 2 easy and secure steps.
