Decent value considering what you get but with some areas for improvement:

  • 3 RGB fans (plus 1 non-RGB)

  • Tempered glass side + (acrylic front)

  • full covered psu shroud

  • lots of extra room in this case if someone wanted to do custom-loop watercooling

  • lots of cable management options/tie down spots in the back


  • no top fan or radiator mounting (I'm thinking about modding the case to do that)

  • case is made of pretty cheap material (flimsy metal)

  • airflow isn't great because the front only has top and bottom slots to intake

  • no cable routing grommets (still dont understand why some cases dont have these)

  • no 2.5" trays for SSD's (WHAT?) and no good positions for mounting them either

  • fans are pretty cheap and do not have RGB rings (just fan blade leds)

A case that is meant to look good. I absolutely love its design, as both the front and the side look astonishing. It even includes a cover for the power supply and cables that might come with it, something that is appreciated for cases at this price. Even more, it comes with a stained tempered glass panel I'm in love with. Of course, some cuts had to be made, reason why it did't get 5 stars. First, instructions are vague and installing the front fans was confusing as many adapters were included but there wasn't an explanation of where they had to go. The fans aren't really RGB (at least they aren't using MSI Mystic Light) since MSI's software only lets me choose between 12 colours. The cooling is not the best as there aren't many gaps for air to go through, though 4 included fans pull a lot of air. There's only one SSD front mount and it isn't completely steady (only one screw supports it). Finally, there are many gaps for cable managing, but none have rubber grommets. All in all, the case does its job really good but some details must be noticed.

I absolutely love this case but I do have one problem with it which I will list at the end of my review. I love the look and RGB fans on this case. While you can only choose from a select amount of colors, I love the different effects you can add to the LED's on the fans and on my MSI B350 Tomahawk motherboard which came with LED lighting it. They both synced up perfectly and make my build look sooo good. The problem I have with this case is that the front panel severely blocks air intake from the 3 fans in the front of the case. The bottom opening barely even lets air to the fans so they are left to the top opening which is so tiny. I find myself taking off the front panel which I am doing heavy tasks that will produce some heat in my system. It is so bad that you can barely feel the fans pushing air with the front panel on but when you take it off, the fans push air to back of the case. Other than that, I love the case and it fits all of my needs as a complete beginner builder with an eye for good looking parts in my pc. Check out my build to see what it looks like!!!

Great case! The only reason why I dropped a star is because you need to take the front of the case off if you're running a 240 mm radiator because you don't get much airflow they added it some red and white finishing pieces for the top and bottom of the front of the case cable management is ok you would have more luck with round cables not flat like mine

Looks great. Premium for the price. Not great airflow though. Still great value.

By far one of the most disappointing chassis that I've ever worked with. First and foremost, the airflow is incredibly poor with my idles hovering around 45°C on both my CPU and GPU. I removed the mostly aesthetic plastic front panel and I dropped my idles by nearly 20°C. This is, in my honest opinion, a grave oversight in Cooler Master's R&D dept. and while it's not exactly lethal to a rig, it's definitely not helping in providing optimal performance for a rig of any caliber. Now, moving to what's under the hood. The shroud is a nice touch and it has several points to run cables through, it's not one solid piece. However, this also presents a problem and that is very little wiggle room for PSUs. This problem is exacerbated by the 3.5" drive cage placed directly next to where the PSU goes so if you've got a larger PSU you may have some issues running cables from the unit. This problem is compounded if you're like me who doesn't solely rely on solid state for your storage needs. Speaking of storage, the case comes with a little tray used to mount 2.5" drives in the case. There are several points where this tray could be mounted but you are only provided with one. At the time of me building my rig, spare trays were not available for purchase from Cooler Master's website. I do not know if this is still the case, I would honestly hope not. Overall I cannot recommend this chassis due to the glaring airflow issues and the poor storage expandability. You're better off going with almost anything else.

Great looking case. Thats about it, This was my first PC build and I wish that I had been able to do it in a different case and maybe I would have had an even better experience. The Airflow is horrendous, virtually no front intake area, NO top intake options. Also, cable space behind the motherboard tray is about 1/2" which barely squeezes my main 24 pin power cable in there. No rubber grommets in the cable holes makes it hard to make the display area look clean. Wouldn't recommend unless you're a case modder.

Wish case had more room for fans and bigger ones two. Additionally they should've made more airflow come from the front.
