All in all I really love this case! this was my first Micro ATX build so there was definitely some frustration trying to fit everything in, but after a little trial and error it turned out great. Pros: Very sleek and slim easy panel removal fits up to 6 120mm fans Cons: very tight fits for almost every single component. it can be difficult to plug/unplug cables from the motherboard once everything is in place Other Thoughts: Idk why there is a dust filter at the top of the case. Most setups will use that as an exhaust vent, not an intake. I was getting CPU temps of 95C under 100% load and I couldnt figure out why.

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 p...

Great case in almost every aspect. The biggest set back for me is the lack of instructions/information in the manual. Especially when it comes to the ARGB configuration. Maybe setting up the ARGB lightning was confusing to me because it was my first time building a PC? The 2 fans use a 3-pin power cable, as well as a 3-pin ARGB cable, which didn't match up with the other fans in my system, so I wasnt able to use the splitter like I wanted to. The front fans are also not overly powerful. It being a microATX build, I expected temps to be a little higher than usual, and they were just that, a little higher than I expected, but nothing you can't fix with some additional quality fans.

It's a nice , entry level builder's model. No real bells and whistles , just very well-thought out. And it has nothing but airflow. The 2 fans that come with it are cheap as all getout , run of an adapter , not a motherboard hander , and don't have a 3 or 4 pin plug , they'll get you into the argb game , but just enough to immediately look for proper replacements. If you're new to this PC building stuff , the case is fantastic with all rolled edges , no weird arcane steps to be functional. And for anybody that ever had the Darkflash DLM-22 , it's about the same size but with one distinction , it does what a good case should do , flow air and look reasonable doing it.

The media could not be loaded. I used this awesome little case to do a Dell "Opti-Flex" swap. Basically I swapped an optiplex motherboard, cpu and ram into this case with upgraded gpu psu and ssd to make an awesome gaming pc Pros -moves lots of air! -decent cable management -tempered glass -rgb fans can be controlled via included remote or motherboard controls and has extra extension which I hooked the liquid cooler up to - can fit a full size gpu - comes with nice ssd adapters so you can install under gpu or behind motherboard Con(s?) - only thing that I can think of would be maybe add a rear rgb fan but for the price I wasn't expecting that. For the price and features cant Beat this. Best micro atx case hands down

The media could not be loaded. This will be my first build as this box was highly recommended from a guy on YouTube. So far I estimate my total spent for the build will be around 2k give or take a couple hundred. I probably upgrade to a better gpu late in the year once the market gets back to normal. I'll update with pics once I complete the build. Update! Finally finished my build. Took a little trial and error but it came out awesome! No Cons. This is a perfect ATX if it's your first build or new. Crazy amount of airflow.

The quality varies from acceptable to good. The glass panel is sturdy and held firmly in place. The back mesh panel is very thin, so be careful with your I/O shield and graphics card instalation. Airflow is good and the fans do well. The RGB is easy to connect and looks nice. I'm a little disappointed at the lack of an exhaust fan, but that's part of the low price, I suppose. There's plenty of room for a graphics card and AIO, but some of the very large air towers will not fit. Make sure to check the specs. Overall, it's a nice looking, roomy little case. For most folks it will be just fine.

This is by far the best MicroATX $60 case on the market. Comes with 2 ARGB fans for that price. I got the mesh but they do have it in tempered glass front. Both case have a tempered glass side panel. Pros: 1. The 2 included fans are ARGB. Also has room for up to 6 120mm fans. 3 up front 2 on top and 1 in the back. 2. Plenty of room for SSD's and 2 3.5 hard drives. Cage can be removed also. They only include 2 ssd's mounts which some might say is a con. 3. Cable management is good and they do include zip ties. 4. Plenty of room for a size-able video card. 5. Solid construction high quality and I never cut myself on anything sharp lol. Cons: 1. Not a fan of the ssd mounting as I was confused on how it worked. 2. No rubber grommets but for $60 I can see why. 3. After ... MoreThis is by far the best MicroATX $60 case on the market. Comes with 2 ARGB fans for that price.

No rubber grommets but for $60 I can see why. 3. After putting video card there is very little room for it to breathe. There is 2 places to mount ssd's under the video card why? I have no idea as it would make the video card work harder for airflow. 4. Dust filter under power supply is removable but, is way harder to remove as it is not the side in type. Top air filter is magnetic why they could do the bottom they same is beyond me. 5. Tempered side panel does set flush with case but be careful when taken it off. Nothing to hold it in place after you remove screws and will fall. Be careful! Tempered glass can break if you drop it on a corner. I really like this case as I believe it is a nice case for what you get for the price. I would like to see in the next version Cooler Master make the bottom dust filter either side in and out or do it like the top with magnets. Cheaper version without ARGB fans. Maybe make it in white. Options would be nice like rubber grommets.

This review is for the Cooler Master MB311L. I bought this case for my first attempt at building a computer. I wanted to build a Micro ATX form factor build and saw this in a video on YouTube. I really liked the Tempered glass side panel, & that the thumb screws used to secure both removable side panels stay attached making it hard to lose them. I found the case easy to build in & there were plenty of cutouts to route cables. I found an adequate amount of room in the backside panel to route cables. The case has a mesh front panel & top panel giving it plenty of ventilation. The fans that come with the case are ARGB & seemed nice, however I could not use them as my motherboard had only 4 pin PWM connectors & these fans were 3 pin. I ended up swapping them out for ... MoreThis review is for the Cooler Master MB311L. I bought this case for my first attempt at building a computer.

good scale micro-atx case
6 April 2021

-overall this case is quite good at its pricepoint, the thick glass and well thought out design allows for easy and clean cable management. this case is about as small as it can be while also being very compatible and still following a typical tower layout. the front panel snaps off for easy adjustment. the only gripe i have is the argb fans that comes pre-installed sound lower quality then other fans i've heard at higher loads. there is just barely enough clearance for 3x120mm in the front
