Internals
With the Stacker's outsized dimensions and clean aesthetic (in this reviewer's eyes at least) covered, it's time to take a look inside.
You can seen the large mainboard area, easily large enough to take even the largest ATX mainboards available. Note the cutout in the mainboard area on the right. That's where the X-Flow fan is mounted, so use of a very large ATX mainboard that covers that hole will render the X-Flow fan mounting redundant. More on the X-Flow fan shortly. You can also clearly see the space below the ATX mainboard area that's used for mounting a second PSU. There's a mesh grille on the bottom floor of the Stacker, as you can see in the photograph. The grille is removable, should you wish to gain access to the hole for a watercooling or chiller project.
The 120mm exhaust fan is visible on the left hand side and the cabling for the front-mounted expansion ports is dangling down on the right. You can also see the Molex power connector for the top-mounted chimney exhaust fan.
The left-side panel has an internal mount for an 80mm fan, to let you intake or exhaust air through the mesh.
You can see the mesh covering on the drive bay covers in the following photograph.
Let's have a look at the drive retention mechanism and the X-Flow fan.
