Final Thoughts

There isn't a lot to dislike about Raidmax's new mid tower offering, and it has some novel ideas behind it; but there are things that leave it wanting compared to other similarly priced cases. It's a basic case with some innovations, such as the entire front faceplate is nonexistent, replaced by filtered, easy to remove bay covers. On the other hand, I don't care for the lightweight 180mm fan Raidmax chose. Then again, you can swap the 180mm fan with a 120mm if you wish. I also don't like the fact there is a total number of three fans, but three fans should be enough to cool your rig, unless you're into serious OCing or live in an unusually warm place.

Think about this, though: You're main cooling is going to be two fans, one back and one side. So, if that doesn't do it, your out of luck, unless you water cool. Personally, I'm also not a fan of backward mounted drives, either, as opposed to side mounted drives. Again, even with the backward mounted drives, you get almost 12" of video card space. The point of this comparison is that there are many mid tower cases in this price range that (a) have more fans; (b) have side mounted drives, while offering nearly the same options as the Seiran elsewhere. I mean, when looking for a case, it's not about one case. You obviously need to compare cases, and one or the other will be the winner for you based on your needs. With that explained, let's continue our comparative analysis.


There are some nice upgrades over the budget Raidmax Blade mid tower, such as a little rubber on the feet, more drive locks, drive caddies, more general internal space, easy to remove front bays for cleaning or general access, and more cable space. But that's compared to a budget mid tower, and the Seiran isn't a budget case. Comparing it to other similarly priced mid towers tells a different story.

For instance, while the Seiran has an LED dimmer switch and a painted interior, the Cooler Master HAF 922 does not. However, the 922 has 200mm fans x2 with the option of mounting a total of three 200mm fans, plus an optional bottom 140mm fan, for a total possible of five fans! The Seiran has a total of three fans, with only one having a size option of 180mm or 120mm, but the 180mm option is very lightweight.

As far as value goes, if you can get the Seiran down into the 70ish USD range, then it's value is looking much better; but adding insult to injury, we have the Cooler Master Storm Scout at Newegg for 70.00USD, which also sports more fan options, side mounted drives, a painted interior, and four front USB 2.0 ports, but not a USB 3.0 port (Storm Scout review at Benchmark Reviews). At the 99.00USD range (MSRP), well, in my opinion, the Seiran is simply outclassed, having tons of scary competition, such as Cooler Master's HAF series. A quick search shows me that the CM HAF 922 can be had for 90.00USD! As I mentioned beforehand, the competition in this range is not only fierce, but predatory. As always, compare before you buy.

Raidmax Seiran Conclusion

The Raidmax Seiran is definitely a step up from the Blade mid tower I reviewed earlier this year, but that's expected, since the Blade is a budget case. There are some nice upgrades and innovative design improvements too, such as drive caddies, tool-less lock downs for both sides of the drive, a completely open front end that is comprised of unique and nice looking filtered bay covers, and a very roomy interior, boasting almost a full 12" of video card space (Thanks to the unique staggered drive bay/fan mount implementation).

Appearance is a subjective matter, but the Seiran is a bold aesthetic squarely aimed at the gamer market. The side panels are good looking and not overdone. The back of the case looks nice too with red mesh slot covers and a blue bladed fan. The front I/O panel is also clean and unobtrusive.

The construction of the Seiran is adequate but nothing to awe over. It's thin side panels feel tinny. Putting a micrometer on both the side panel of the Cooler Master Silencio 550 and the Sieran confirms this: The Silencio measures 00.03" while the Sieran measures 00.025". Overall, though, the case is plenty sturdy, and light. The internal paint is a nice touch, and so too for its nice, thick, beefy, filtered front drive covers. The panels were some of the best fitting I've used, coming off easily, and more importantly, going back on positively, without those infuriating line up errors.

Functionally speaking, it does what it needs to do, except it's a little light on fan power, with a maximum of three fans total. There is tons of space in the Seiran, however, with almost 7" of cooling tower space and almost 12" of video card space. The drive mounts are your traditional back facing into the motherboard area. Cable space is adequate to good, but not great. With a total of nine drive bays, you should also have plenty of drive space, and with seven expansion slots, enough room for expansion cards too. The front I/O panel has both a fan controller and an LED fan dimmer switch, plus one USB 3.0 port, along with the normal I/O ports and two USB.

With excellent cases, not good, not decent, but excellent cases running in the $80-90 USD range, the value for the Seiran is a little on the low side, if it comes in at around the same price. If it comes in at around $99, then comparing it to other offerings, it's options are outclassed. It's a decent case, but better cases can be had for the same or lower price. If, however, you like the design and the unique features of the Seiran, you won't go wrong buying it. It's not a bad case at all, and it's decent looking and easy to get to the front without pulling any faceplates off. It's just not excellent in the areas other cases are already excellent, and for the same price.

For these reasons, like the Blade, no special recommendation is given this time based on my analysis and the competition; but I would like to stress again that the Seiran is a decent case by any standards, with lots of interior space. It's just not up to a recommendation based on other like priced mid tower cases available (e.g, Cooler Master's HAF and Storm series). Please let me know what you think about my analysis because this is really the hardest part of the review. The people at Raidmax are people too, and their just trying to make it like the rest of us. If you think I'm being biased or unfair, let me know how or why in the comments section.

I like the completely open front accessibility. I hope to see that design in other cases. Other things were less desire able, however, one being the price.

Hi Doug, I enjoy your reviews and I think you did a great job of giving us readers the next best thing to being able to put hands on the thing. it appears that it's a bit 'thin' in some of the construction.
"plasticware, or "steel-astic." good god man! I think you just Shakespeare'd all over yourself LOL.
On page one , I think you probably meant 'beveled' as opposed to "cantilevered"
anyway, nice review. I am looking for a gaming case for my nephew, and I think you have ruled this one out for me :)

Hey tanks. I'm glad someone is reading them and seeing the subtle interjections that are my attempt to prevent "reader bore-fatigue."

And yes, I will have it changed to "beveled" as "cantilever" has a completely different meaning. Thanks.

I have another review due out in the next couple of days. It's of the Rosewill Ranger mid tower. It's not a bad case and if you need cooling, it's a wind tunnel. I actually gave it a recommendation.

Super review. I really appreciated all the pictures and text. What I don't like about the case is the rear facing disk drives. I want the drives facing toward the side. If you make drive changes, the rear facing drives generally require you to remove the graphics card.

This case shows us that the techs from Raidmax know how to create a decent PC case too. Good job.

# Xigmatek fan?Mergatroid 2011-12-13 16:44
That 180mm fan really reminds me of Xigmatek fans. Specifically the 200mm fans available from I believe those are the same fans used in the original Corsair 600T case. Many people (including myself) replaced them due to poor performance. They sure look similar.

Personally I don't see much to like about this case. I suppose it's pretty good for $100, but as you mentioned there are other cases in that price range that IMHO are better cases. Personally I couldn't do without removable drive cages any more. I also prefer sideways mounted cages over the front/back older style cages because you can completely hide the cables. I know looks are subjective, but personally I think this case doesn't look very good. I don't like the window design, nor the front bezel, nor the convex design on the right side panel (I realize it may be very functional for cable management, but I don't think it looks very good myself). I also don't like the big latches on the 5 1/4" drive bay covers (I think they could have found a better way to spend the development funds). Considering how seldom you have to remove them, I really don't mind interior plastic clips if it avoids big ugly latches on the exterior. I really don't like the big square front panel at all.
I suppose for $100 you could do worse, but there are better cases available for about the same price.

Here's a test fit I did of one of the Corsair 200mm fans on the optional (at the time) side panel mesh for the 600T. Looks pretty similar to me.

# RE: Xigmatek fan?Doug Dallam 2011-12-13 17:03
Megatriod. I think I'm pretty much with you on that. There are, in my opinion, better cases for less than 100.00, as I pointed out. This case, again, in my opinion, is simply out of its class at 100.00. We'll have to see what price they actually come in at when available. But the Rosewill Ranger, which is now published too, I think is a better case, functionally speaking, and it's intro price is 70 bucks! It has the side mount drives and can take up to seven fans, five of which can be 140s, with some limitations. You'll have to read the review for the rest :)

That sounds like a better option to me. I'll have to check that review...
