RAIDMAX Seiran computer case review

RAIDMAX has been on a roll recently launching a plethora of good looking cases on a budget (check our Raidmax Helios Review) and their latest addition, Seiran (MSRP $79.99) is even more ambitious than the other members of the family, at least in terms of specifications. Beside the good looks though, more important is the provided space, ventilation system, motherboard form factors that it can accommodate, overall sturdiness and the degree of finishing, etc. We’ll try to cover all these questions and more in our Raidmax Seiran Review and help you make an informed decision, so read along.



The box was shipped double packed which is usually a good sign. Inside the main box, the original and quite attractive Raidmax Seiran packaging containing the PC case itself and a number of accessories to help with the cable management and of course, a small bag of screws, spacers and even a small buzzer, pretty much everything you need for a successful installation.



Raidmax Seiran Design

Outside, the Seiran is quite a looker sporting a very elegant design. I like to balance features and aesthetics in my purchases and Seiran offers the best in both worlds. Seiran features an extremely spacious interior capable of accommodating full size ATX motherboards, an elegant exterior offering a well matched color combination (at least on the black Seiran case I am reviewing) and 9 x 5.25″ external drive bays should satisfy even the most demanding gamer. On the top-front you will immediately notice the control panel providing two USB 2.0 and one USB 3.0 (nice touch!!!), the standard microphone – headphones ports, power button, reset button, the standard HDD red LED light and green POWER LED light, and, a dual channel FAN controller installed for good measure. The raised control panel also acts as a handle to help you move the case around if needed.


The number of drive bays available means you’ll need some good cooling in case you are thinking of filling it with storage devices. The cooling is provided by two 120mm fans (a lighted one in the front and a regular one in the back plus the optional (in the specs, mine came with it installed) huge and lighted 180mm fan installed on rubber washers on the side door. It is big, quiet and the volume of air displaced by it significant.

Internally, Seiran provides 4 X 3.5″ H.D./2.5″ SSD Racks for newer storage devices, racks that are borrowing the space from the upper 5.25″ bays so it is not a real 9 + 4 bays. However, the storage space offered is significant and can qualify the case as a home server case as well, especially with the lower power green hard-drives available.


Design wise, I like the  following elements:

  • water cooling outlets in the back
  • bottom PSU with a removable dust filter for those PSU units that are pushing the air in that direction
  • large number of storage bays
  • the new cover system for the 5.25″ bays, easily removable with one push of the button

The not so optimal design features are the back handles that when closed are obstructing part of the water outlets and the extension card outputs, but you can easily move them in a different position so it is not something critical.

Installation and testing

For testing, I used a nice GIGABYTE GA-990FXA-UD5 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard together with an AMD Phenom II X6 1035T Thuban 2.6GHz Socket AM3 95W Six-Core Desktop Processor and a Cooler Master Hyper 212 EVO aftermarket cooling system. I was a little bit worried about whether the Seiran will accommodate the significant bulk of the 212 EVO cooler, but amazingly enough, everything fit right on. The GIGABYTE GA-990FXA-UD5 is quite big as well, but as you can see from the pictures, it fit without any problems in the Seiran as well.

I decided to test the case with an original RAIDMAX power supply, the RAIDMAX RX-1200AE 1200W ATX12V v2.3 / EPS12V SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply which is quite a monster in itself. It fit properly at the bottom and the removable air filter on the bottom was put to good use. The video card? A hefty GTX 590, several pounds heavy and 350+ W thermal envelope. All in all, a setup designed to deliver a significant amount of heat and test the Seiran cooling capabilities and noise level.

Some oddities I feel needs to be addressed – the cables have no labels. If you are an experimented system builder, you can figure out from the connectors shape which cable has what function, but it would be a good idea in future iterations to attach some clear labels onto each cable.


Cable management system

The fixed side is profiled to allow various cables to pass under it (the motherboard gets installed over a kind of platform. Nothing to write home about but it does an absolutely decent job of hiding the SATA cables, and if you are using a lot of the hard drives, as permitted by the case design, you will have a lot to hide. Nice touch and good to see a decent cable management system in such a low priced case.


This is where in my opinion Seiran really shines. Providing a generous nine external 5.25″ bays and 4 internal 3.5″ / 2.5″ SSD racks (which take some of the external bays space), Seiran is more than ready for the today’s storage needs. In fact, I am so impressed by the storage capability that I decided to move my home server (which has exactly nine harddrives installed in a server case) into this new case. It stands vertically so occupies less space than my desktop server case and it provides a much better layout as well. All the storage bays offer a tool less mounting capability to easy mount your harddrives.


Noise and cooling

Even fully loaded, the case kept cool due to its dual 120mm fans and to the huge 180mm side fan. The bottom air filter also helped the massive power supply cool and, depending on your load, you can use the fan controllers to make it almost silent under light loads. All in all, Seiran provides a good air flow (direction front to back) and is very quiet at low to average load.


I was impressed to see a high quality case coming at a budget price and I really like the aesthetics of the case. Personally I prefer the black model, but your tastes might differ. The water cooling outlets are convenient as it is the tool less operation, the high number of storage bays made it instantly my favorite case and I have to say RAIDMAX really stepped up its offering with the launch of Seiran. The MSRP is $79.99 and should be soon available.


  • good looking with elegant but fairly subtle design
  • tool less operation
  • large number of storage bays
  • attractive and easily removable front drive covers
  • enough space for the largest ATX motherboards
  • USB 3.0 port in the front
  • bottom ventilation hole with removable dust filter
  • price


  • no labels for the internal cables
