There’s also an assembly manual that is going to be of much help if you try to transform this case for the BTX format. Yes, this system case is originally designed for mainboards of ATX as well as BTX form-factors!
Note that the face panel has faceplates for 5.25” bays almost from top to bottom: you can put as many as eleven 5.25” devices into the CM Stacker in total. There is a slot for a 3.5” device, too, in the topmost faceplate. The faceplates are curiously designed: a metal grid attached to a plastic base. You can remove the grid to clean the air filter inserted into the faceplate and then put the grid back.
Six USB connectors, one FireWire connector, audio connectors, Power and Reset buttons, HDD and Power indicators are all located at the very top of the face panel of the system case. This is a sensible solution since the most likely place for such a large system case is the floor.
The wires extending from the USB and FireWire connectors into the case end in four double-row connectors. It’s just impossible to plug them wrong. The cable from the external audio connectors ends in separate single-row plugs. The connectors are all labeled, so you shouldn’t find it hard to connect them right, either.
The left side of the case is, again, aluminum (the right side panel is made of this material, too) and is fastened to the case with two thumbscrews. There’s a 300mm hole in the side panel: it is covered with a decorative grid and there’s a dust-collecting filter under the grid. This looks most originally, but having removed the side panel I couldn’t find a 300mm fan on the reverse side. To my disappointment, there was just a place for an 80mm fan in the center of this large air inlet. This seems very disappointing to me.
