External Overview
The Raidmax Seiran is a very open case with much expandability. It’s available in three different colors, black, red, and white and includes plenty of cooling options. Three fans are included and work well with its mostly mesh design. Despite the mesh, the case looks like a plain old rectangular case with some plastic additions on the front/top. The entire front panel of the case is made up of 9, 5.25” removable mesh bays, allowing you to move your drives anywhere you’d like.

On the top of the front panel are your front access ports, which include two USB 2.0, a USB 3.0, and audio/mic jacks. Also included are your standard power/reset buttons, activity LEDs and two knobs, one for fan control, the other for LED brightness control. The front access ports also act as a handle for the case.

The front mesh bays are black with red plastic behind the clips that let you easily remove them from the outside of the case.

The side panel is mostly composed of a black mesh, of which you can see the included 180mm red LED fan.

The rear of the case, while pretty standard in terms of layout has some interesting colors visible from the rear.  Starting from the top you have your motherboard I/O and rear 120mm exhaust fan with blue fins.

Moving further down are your reusable red mesh slot covers, three water cooling holes and bottom mounted PSU slot with removable filter.

Both side panels are equipped with two thumbscrews and a foldable handle for easy removal.
