If we are looking for veteran manufacturers in the computer hardware field, Cooler Master should certainly count as one of them. Best known for their quality cases and coolers (as if their name didn't give that part away), the Taiwanese company has grown to focus not only on OEMs but enthusiasts and gamers. About a decade ago, Cooler Master introduced the Stacker series of cases. These were massive enthusiast-class cases, employing a weighty metal construction suitable for stacking and storage expandability almost unheard of in the consumer market at the time. Several years later, the gamer-centric HAF series was introduced and touted High Air Flow for heat-blasting graphics cards and overclocked processors. Since the debut of the HAF 932 full tower, the lineup has widely expanded to encompass mid-towers and even cube-shaped cases like the HAF XB. Unlike the Stacker series, HAF cases substitute all-aluminum designs for mesh, large fans, and more rugged looks.

Today, we will be taking a look at the HAF Stacker, a merging of the expandability and stackable stature of the original Stacker with the industrial look and airflow potential of the HAF series. What's unique here is the innovative modularity in the HAF Stacker design. You see, the HAF Stacker is more of a series of cases than one specific enclosure. Currently, there are three version of the HAF Stacker: the mid-tower HAF Stacker 925, m-ITX HAF Stacker 915R, and m-ITX HAF Stacker 915F. The default HAF Stacker configuration ships with the first two cases above, which together are dubbed the full-tower HAF Stacker 935. Stacking an additional HAF Stacker 915 then forms the HAF Stacker 945 ultra-tower. Officially, Cooler Master touts the entire series as a "mod tower", allowing for virtually limitless storage and expandability options, assuming that money isn't an issue and the resulting tower doesn't fall over!

For all intents and purposes, this will be a large review (we are basically reviewing 3 cases) with a greater emphasis on the full-tower capabilities of the HAF Stacker 945 configuration. A later review will observe how the HAF Stacker 915 m-ITX cases fare on their own. Without further ado, let's take a closer look at the HAF Stacker and see how it stacks up to other cases on the market (no pun intended).
