Cooler Master HAF Stacker 935 Closer Look:
Looking at the main unit, you will notice the standardized look of the Cooler Master HAF series, with the beehive mesh and Cooler Master emblem low and center. Looking at the left panel is home to a large tinted side widow that shows 90% of the inside. The window itself has no fan mounting options and the right panel is solid, also without any fan mounts. Cooler Master did, however, state the ability to replace the window with other solutions like a 200mm side mounted fan. Next, looking at the top front from left to right, is the I/O power button, mic jack, headphone jack, one USB 2.0 port, two USB 3.0 ports, and one more USB 2.0. It's worth noting (and unfortunate) that Cooler Master chose not to include a reset button, as when the system locks up from an overclock, the power button tends not to work. This can cause some problems for overclocking enthusiasts, but for the rest the lack of a reset button might not be noticed at all. Cooler Master's response is as follows: "We decided to omit it to simplify cable management. In modern systems, a power switch can do the same task of both a reset and power switch."
Lastly, the back includes a 140mm fan, eight PCI expansion slots, and a space for a bottom mounted power supply.
The top of the main unit is a bit different. Normally you would have some sort of panel, but in this case, due to the unique stacking feature, the chassis does not come with a top cover. Have no fear, as the default setup is to have the 915R chassis slide into place allowing it to act as a top cover. The bottom has the same rail system but with raised bars to act as feet. If you are opposed to placing the 915R chassis on top, you can switch the bars around to allow it to be placed on the bottom. Next, you can also see the fan filter for a bottom mounted power supply with two rubber flaps allowing wires to flow once again between chassis if you have another 915R or 915F on the bottom.
Removing the front panel was fairly easy because of the clips. Once removed you see options for two 120 mm fans or, with the hard drive cages removed, a 240mm radiator. It is also worth noting that these chassis did not come with a front fan, which can be a concern because of low air flow. My thoughts are that Cooler Master assumes you will be adding a radiator that includes fans. The other option could be Cooler Master figures you will be replacing all the fans with your own preference so why include fans in the first place? Cooler Master's offical statement is what I guessed: "In a survey of our HAF users, most users immediately upgraded all the fans in their chassis and removed the standard ones. Out of the box, the HAF Stacker is configured for sufficient cooling for average PCs. Having a basic amount of standard fans enables our users to choose the fans they prefer, such as Jetflo fans."
