Stacker 935

The HAF, or High Air Flow case design has been around since 2008, in 2013 they introduced a new model, the Stacker. The Stacker is a stackable “mod-tower” that takes their experience with the HAF line and expands it to an easily expandable case. At the heart of the Stacker line is a mid-tower along with two ITX cases, the 915R and 915F. These can be combined in any configuration to meet the users need. The basic combo model is the 935, commonly referred to as HAF-935-KWN1, which includes the mid-tower and the 915R. Combined, the 935 is a very large system coming in at 9.255 X 28.8 X 22.75 (WxHxL), and includes a 2 year warranty; the Stacker 935 currently sells for $169.99 with free shipping at when it is in stock.

The two 915 models are much smaller as they support only mini-ITX systems, and can be configured to support custom liquid cooling solutions or they can be configured to support up to 9 3.5″ hard drives (additional hardware is necessary). Between the two models of 915, there is a slight difference; one has a Rear mounted power supply (HAF-915R-KKN1), while the other has a Front mounted power supply (HAF-915F-KKN1). The 915 models are relatively small, measuring only 8.97 X 9.76 X 22.75 inches (WxHxL). While the 915R is included with the 935, it is also available separately. The smaller 915 models sell for $69.99 shipped at Amazon.
