While the Seiran might not be as edgy and futuristic looking as some other Raidmax cases, it does come in some pretty snazzy color schemes like white/blue and black/red. We received the predominantly red model with red exterior and red LED fan lighting. Black mesh, motherboard tray, and feet help balance things out a bit. The front panel is covered in nine 5.25" bay covers that are easily removed by plastic latches. A dust catching foam material is present on the back of each cover. The topmost cover can be removed in favor of a 5.25" to 3.5" adapter. Power and reset switches, indicator LEDs, audio line-in/out, two USB 2.0 ports, one USB 3.0 port, and two knobs occupy the case's face. One knob controls fan speed while another manages LED brightness. Behind the control unit, we find a very convenient handle. It was satisfyingly easy to manhandle this case given its low empty weight.
Turning the Seiran to the side shows off a very large grille with rubber fan grommets for either a 180mm or 200mm fan. Builders will need to take special care to avoid snagging the fan's power cable on its delicate blades. A red 180mm LED fan comes pre-installed. The opposite side panel is perfectly flat (current production side panels have bulges) and both feature plastic handles for easy removal after loosening the thumbscrews. Taking a look around the back, we find seven expansion slots, three grommeted water-cooling ports, and space for the included 120mm fan. There's also removable PSU filter tucked neatly between the rear set of plastic feet.
It might look like a Ferrari, but the build quality of some parts on the Seiran would suggest otherwise. The side panels do exhibit a bit of flex given their low-gauge steel build, and the plastic knobs and buttons on the front panel feel quite cheap. It's relatively easy to notice a couple of seams here and there, but the Seiran didn't creak when we poked and prodded at its insides or wobble when we set it down. After having owned several Raidmax cases in my early building years, when they offered gaming cases that looked "cool," I was often greeted by cheap metals and other build issues. The Seiran is leaps and bounds above the "Old Raidmax" I remember in terms of build quality, although they still cut a couple corners in the name of being budget-friendly with the Seiran.
