The top panel of the Evolution can be seen in Figure 6. It has a mesh, supporting the installation of two 120 mm fans. Two of the highlights of the reviewed case are found on its top panel, its two-channel fan controller and its hot-swap docking bay.

The analog two-channel fan controller allows you to independently set the speed of two groups of fans. Each channel supports up to 1 A, which translates to 12 W at 12 V. The case comes with one adapter allowing you to connect up to three fans to a single channel, so you can control up to four fans (although three of them will run at the same speed). This controller uses three-pin fan power connectors.

The case also comes with two USB 3.0 ports, which are attached to a motherboard connector instead of regular USB plugs, so you won’t need to route the USB 3.0 cables to the outside of the case and install them on the USB 3.0 ports located at the motherboard rear panel. When buying this case, make sure to buy a motherboard that has at least one front panel header with two USB 3.0 ports available.

The Evolution also has two USB 2.0 ports and the traditional audio jacks.

The hot-swap docking bay is hidden by a lid with the manufacturer’s logo. By pushing this lid down, you can install a 3.5” or 2.5” storage device.
