    • Decent for the price.
Style: MB511 Size: ATX Mid-Tower
I'd probably rate this a 3.5 if that were an option, decided to round up to 4. I got two of these on sale for about $65 each, if I had paid full retail ($115), I'd probably feel ripped off. Pros: Lots of space. The two builds I put in them were budget builds so the graphics cards (6600) are small and the processors (5600) are just using their stock coolers. I'm confident that the case is more than big enough to support the longest graphics cards and most if not all after-market CPU coolers. The stock fans are relatively quiet, provide decent airflow, and the RGB seems fine if you're into that sort of thing (I'm not but my kids love it). The case has very good airflow with all the space and mesh panels. The tempered glass looks nice and is reasonably thick. The case itself feels very solid, being mostly metal parts. Cons: The tempered glass panels have one side with screws, and the opposite side has a U-shaped piece of metal that slides around a thin piece of metal in the case in order to secure it. One of the U-shaped pieces of metal came bent, making it a pain to take off and line up the screws. Not a big enough deal for me to try and RMA it, but annoying none the less. The cases would be pretty loud if I had better components with bigger/louder fans in it, but that's just how it is for every case designed to maximize airflow as far as I'm aware, so that's not really a problem for this specific model - a tradeoff for the good airflow it offers rather than a true con. The mount for SSDs is directly above some of the back plugins for an ATX motherboard where you would plug in the sound, power button, etc., from the case into. This is why this case gets a 3.5 and a full review from me instead of just a "5/5 good case". The case has SO MUCH SPACE, and yet it felt so cramped when I was plugging those wires in. I removed the SSD when I did it of course, but then I had to bend some wires out of the way to get it back in. There's just no need for that, if that mount had just been an inch or two higher, which there is more than enough space for, or if it had been put somewhere else entirely, there'd be no issue. I had to use my drill to get out a couple of screws that were holding the drive bays in (which make the space for the power supply needlessly cramped, I'd probably be whining about that as well if I had to actually use the drive bays and leave them in), as well as one or two of the screws for the removable grates on the back to stick the video and wireless cards out of. To be fair, the screwdriver in my computer building kit is very thin and hard to get good torque on, if gremlins (AKA my kids) hadn't apparently lost all of my full-size cross point screwdrivers then the drill probably wouldn't have been needed. Overall, now that the builds are put together the cases are completely fine, but it was a bit annoying to build in and I'll probably go a different direction next time. The case had a lot of potential, I think if the space had been better-utilized it would have made a big difference. ... show more

Edit: 10-13-2020- Still using the case, it works great! Note: **You absolutely CAN fit a radiator in the top of the case. ** I have pictures included from my original install that plainly show that it is possible, and even easy. The price has gone up a bit, probably from how popular the case is, but it's well worth it! _______ original review below__________________ I've included screens of my build. Hopefully you can see on the bottom just how "clean" you can make this. I have no external HDDs or SSDs and am using two M.2 drives to make for an extremely quiet build. If you don't read my whole review, be sure to go to the end where I mention something that messed with me for about 2-3 hours that I finally figured out. (A mysterious SATA3 connector.) Going to list off the "pros" of this case: 1. The unobtrusive "cutouts". Cable management is a thing! And they do a great job here on this case. Along the bottom where your MOBO meets the case, there are several small holes that you can hardly see until you buy the thing. If you look at my attached pictures, you can get the idea how I ran the cables up through the bottom and did a quick loop back to plug in items like the HD Audio, USB 2 and in my case, the ARBG cable, etc. 2. Great cutouts on the sides. I expect to get middle cutouts -but these have some nice rubber padding that keeps a minimum of light from showing through. Additionally, they had the perfect set up for hiding the CPU power at the top of the case/mobo as well. (Look closely at the top left to see what I mean...) 3. Airflow. It's hard to get a really good feel for just how much flow is available, but the way they situated the glass panel in the front, and cutouts under the fans as well as on the sides means a TON of air flows through the case. As an added effect, when you look directly at the side of the case, the vents almost GLOW with the color of the fans. I built cases for 20 years and basically poo-poo'd the idea of RGB lighting (or even just plain red or green lights on fans) for years. But about a year ago, I finally got on board, and this case REALLY makes RGB lighting come alive. 4. The fans. Lots of complaints from current buyers for some reason. Again, I have no HDDs, though I do have a radiator. I also have the Asus ROG Strix x470 mobo - and it comes with an automatic fan adjuster (that works with overclocking). I'm running my CPU at a consistent 4000Ghz (about an 8 or 10% overclock) and it runs BELOW room temperature. That's with a coolermaster liquid cooler and this case fans on it. Yes, they stay on and only have one speed, but all things considered, it's super quiet, looks great, and does the job beautifully. 5. The glass panels and the metal panel cover on the back. The glass is legit. It's HEAVY. I've also dropped it, and it's durable. I love the grommets they use - it's the first time I've had glass panels that the screws stayed right inside the panel, and it's got elegant hooks on the bottom that make re-attaching the cover the .. seriously, bar none, and I've been a data center sys admin for 20+ years, and have probably put the covers on literally a thousand servers and desktops - the easiest cover to open, remove and re-attach of ANY PC/Mac/Tablet/Phone, etc etc - that I've ever touched. As for the metal cover - I love how easy it was to attach. I love that when I put the glass panel back on, since the metal is already lining all your cables up, it (again) makes the glass uber easy to put back on the case. (See my attached picture). All those cables (which include PCI-e and power for the MOBO, the fan cables for RBG and power, the case connectors, etc) - all tucked away, nice and neat under that metal panel. 6. Bells and whistles. It's got an extra inch or two of width. Makes fitting in radiators on the top of the case actually a thing. (I had to shop around just to find a case that would do that!) If you read the instructions - and the fact it has its own RGB controller (though it's only a button on the top of the case, so it's rather simplified controls...) that's frickin' cool. USB 2 and 3 (two of each) on the top of the case. I love that the power button has RGB and you can control it. Never, EVER seen a case that let me change the power button color. (Or rotate it along with the rest of the fans, etc). Comes with FOUR fans (One is not RGB, though). Oh, and it's ARGB, if you have a controller (or MOBO) that can take advantage of it. That makes this case REALLY economical. Cons: As someone else mentioned, the area for your power supply is pretty tight. Be sure to test the size of everything first. I'm using a modular 750W PSU, and it fits fine, but I had to plug all my cables that I wanted in first - it just didn't fit/wasn't enough room to try to plug them in after it was tucked in. I originally put my PSU in first, before attaching the modular cables and had to take it back out... Please be sure to look at the advertising material about the case. The pictures that show where your radiator goes are accurate. I used a 240MM radiator on the top and it fits beautifully. (See attached pictures.) It doesn't have a ton of extra screws. That part is true. The instructions are not great. The fact that it ONLY has HDD lights and power switch may throw you for a loop. (I was thankful of this, quite honestly.) There is a connector that came with this thing that REALLY messed with me. It's a SATA3 connector. Just plug it into your power supply. I spent hours looking for what it was supposed to plug into. Other notes (and sorry this got so long! But, I wanted to make sure I put in all the information I could, because this case delivers a TON of value...) Also, the controller cable for the RGB fans included ARE compatible with Asus, Asrock, Gigabyte and MSI. Said controller allows you to use all those manufacturer's motherboards. (One review listed 3 of the 4 above, another person said a motherboard controller couldn't be used at all. Yet, in the bottom row of pictures in Cooler Master's Amazon description (above) in the middle picture you can see the cable right there that allows you to use 4 manufacturer's motherboards.) If you don't have that cable and need it, be sure to return the item and get a version that has the cable. It works great. If you don't have one of the above manufacturers, the button next to the power button works as your RGB controller. (Note: it's not a Reset button. This case only doesn't come with a reset cable or button. Only Power switch and HDD lights. TL;DR: Given that it comes with 4 fans, 3 of them are ARGB, and it's a slightly larger mid-tower that can accommodate a 2 fan radiator (hard to find for less than $150!!) - this is my new favorite case. No, the fans aren't the equivalent of an $80 set, but they're darn close. They are quiet, completely configurable and with all the other bits of hidden engineering (air flow, cut outs, cable management, compatibility with mobo manufacturers, etc) - you get more bang for your buck than nearly any other case. If you check out various review sites regarding this case, you'll see that they agree with me. ;) Nice job, Coolermaster! ... show more
