Inside the HAF Stacker 935
Once the panels are removed, it is much easier to get an idea of what is going on inside of these cases. As for the hardware, it is strapped to the HDD rack in the 925, and the case wiring is tied up and run through a grommet for transit. As for paperwork, there just wasn't any inside of this box.
At the top of the 925, there are three 5.25" bays with tool-free mechanisms on this side of the bays. This plus the one in the 915R above this, there is a total of four 5.25" bays in the 935.
Under the optical bays, there are the two HDD cages that hold three drives each. Again there is another section that holds three drives in the 915R, so even if you removed these two racks and the base, you still have room for storage at the top.
There are little holes in the roof of the chassis that would allow users to install a pair of 120mm fans here if the 925 is at the top of the stack. If the 915R is on top as it is here, the cut outs of both cases line up well to easily allow parts to pass from one section to the other.
The motherboard tray will house EATX, ATX, and Micro-ATX motherboards, and even has helper standoffs installed. There are six wire management holes, four of which include grommets, and 12 locations to tie wiring to.
The floor of the 925 has raised pads to support the PSU at the back of the chassis, and as we saw from the bottom, there are large holes with grommets to run things from the bottom section, if you install the 915 there.
The back of the chassis contains the only fan inside of the 925, and while it is powered with a 3-pin header, it also includes a Molex to 3-pin power adapter. All nine of the expansion slots are ventilated and held in place with thumbscrews.
The back of the 915R is completely open, and even the HDD plate from the 915F is gone. As for the 925, there is 20mm of space to run wiring and there is even a 2.5" drive location right under the CPU cooler access hole.
The wiring is kept simple, but all of the wiring is black to disappear into the build. You are given native USB 3.0, HD or AC'97 Audio and USB 2.0 connections. There are also the wires for the power button and the red LED indicating system power to connect.
