The I/O panel is located on the top side of the case. Most of the upper part of the case is occupied by a large vent, under it is room for two optional 120mm/140mm fans or a watercooling radiator.
Here's a closeup of the I/O panel. From left to right we have two USB 2.0 ports, two USB 3.0 ports, a headphone and microphone port, the power button and a tiny reset button. There's also a red power LED and a blue HDD activity LED.
As you can expect from most all-black cases these days, the rear has the same black paint job as the rest of the case. The rear is quite open, there's a 120/140mm fan slot (120mm fan is included), 7 meshed PCI slot covers and two pre-cut holes for watercooling tubes. The PSU is bottom-mounted.
Flipping the case over reveals the four feet and a removable dust filter. As you can see on the picture, more than two thirds of the bottom of the case is a vent to let air into the PSU and the case. One nice touch is that the dust filter is held in place with magnets, making it very easy to remove.
The side panels are secured to the chassis with thumb screws. The left side panel features a large side window.
