Interior design can make or break the functionality of any chassis on the market. The ease of building, cable management, and looks are all important factors when choosing a chassis for your next build. Let’s have a closer look at the interior of the Raidmax Seiran and see how it measures up.

After removing the side panels, we took a quick look at the included 180mm fan attached to the left side panel. As mentioned before, it has a red LED light and also has rubber cushions at the mounting points that help dampen any fan vibrations. There are two power leads coming from this fan, one for powering the fan, and the other for the LED. Both of these leads get connected to the front panel fan controller allowing the user to control both the fan speed and the brightness of the LED. The same holds true for the front intake fan.

The interior is painted completely black and features a very large cut out area in the motherboard tray section to allow for easy removal of a CPU cooler. The wire harness is complete with everything you need to connect the fans to the controller and the front panel USB connections (both 2.0 and 3.0) to the motherboard. The standard motherboard connection wires consisting of the power, reset, HDD activity LED, and power LED are all present.

The bottom interior area is highlighted with the ventilation area for the power supply and a large cut out for cables to pass through.

The inside rear doesn’t really have anything we have not already covered, except for the fan blades, which are a bold red color and match nicely with the black and red theme of the case. The rear fan does not get connected to the fan controller and has the standard 4-pin Molex power connector. Also worth mentioning is the meshed expansion slot covers that allow for additional air flow. The expansion slot covers are held in place with standard PC type screws and not thumb screws.

There is room for nine drives to be installed in to the Seiran case, either 2.5″, 3.5″ or 5.25″ devices can be installed in any of the bays. One issue that we had was that only six drive trays are included with the case. We would have liked to seen the full allotment of nine trays included. Just to the rear of the upper drive bays, there are two rectangular shaped rubber grommet pass through holes for additional cable management opportunities. In addition to these pass through holes, Raidmax has allowed for some extra room between the right side panel and the body of the case, 25mm clearance to be exact. This is a welcome sight as much too often we run across cases that have very little room in this area, making cable management behind the motherboard tray almost impossible.

Installing a drive into the Seiran is a relatively painless task that requires removing the lock plates on each side of the bay targeted for a drive. You simply twist the knob to the open position and remove the lock plate. At this point, you can slide the drive tray out and install either a 2.5″ or 3.5″ drive in it. Installation of a 5.25″ drive does not require the use of a tray, you simply slide a 5.25″ device in and lock it down with the lock plates on both sides of the bay.

The drive trays are another unique design found on the Seiran case. They are both very easy to use and to install drives into.  You just need to lay the drive in the tray, line up the mounting holes, and secure the drive to the tray using screws. Once this is accomplished, you slide the tray back in the desired location and secure it in place with the locking plates.

As previously mentioned, installing a 5.25″ device is just a matter of removing the bay cover, sliding it in place, and securing the drive with the lock plates. Here are a couple of pictures showing a ROM drive installation.

Finally, we removed the front panel to get a look at the inner workings of the fan controller area. The front panel is removed by grabbing the bottom and pulling straight out, much like many other cases on the market. All of the controller area solder joints were nicely done, and the wire leads were found to be of good quality and securely fastened to their respective connection points.

We will finish off the tour of the Raidmax Seiran with a quick look at the accessory box included in the package. The box of accessories were tied securely in the drive bay area and arrived intact. Included in the box were a users manual, an extra 5.25″ drive bay cover, and three adhesive backed wire management clips. Also, included in the accessory box is a bag full of miscellaneous screws, wire ties, a speaker, and motherboard mounting pegs.
