5.0 out of 5 starsBetter than you'd think
Reviewed in the United States 🇺🇸 on September 11, 2022
I was worried at first after reading some of the low star reviews, understanding ordering anything online is a bit of a gamble. BUT, I was one of the lucky ones, This case is amazing! Yes it is THIGHT, that's to be expected, so I tore out the guts from my REDUX pre-built that was Way too large. And it came together without compromising performance. A lot of the bad reviews were about insufficient thermals, considering the case is extremely modular, it's fairly easy to achieve proper airflow if you are creative enough the fan placement, it may have been a different story if I was air cooling rather than water, but my large 240mm radiator fits just fine. Having cool air come from the bottom and front, and exhaust hot out the top and back, my thermals are holding strong. The dust filters are a great addition for aesthetic and functionality. But if you have a 2 or even 3 fan GPU you may struggle to fit it. Overall I'm giving it 5 stars because as a experienced PC builder it was at most a 5/10 for difficulty and a 10/10 for style. Material is sturdy and well put together. And noise is all about fans and airflow so weigh your options there.

3.0 out of 5 starsGood size and features - overheating issues
Reviewed in the United States 🇺🇸 on March 28, 2022
***Edit***
After using this case for 2 weeks, I noticed heat issues when the CPU was under load. I have an i7 CPU, not overclocked, and during Lightroom exports, the core temps were hitting 100. Moving the dust filter to the top helped a bit. I installed a fan in the front, and that helped too, but it made the PC loud, and it was running a lot. I also increased the fan speeds and usage times. I think that the problem is that the PSU is mounted vertically at the top on the front of the case, so it blows exhaust right onto the CPU. That also means that there is no cool air intake. directly in line with the CPU. An intake fan in the bottom of the case doesn't do much, since it's right against the ground, there is a dust filter, and the GPU blocks it. A fan in the front of the case at the bottom of the front panel isn't in line with the CPU. Removing the front dust filter helps a bit, but then the case will fill up with dust.
*****

I was building up a new PC, and I like to keep the tower under my desk, but I only have about 17" of space, so I needed a shorter tower, preferable with the power button and USB on the front or side. Also, I needed a case that would hold an ATX MoBo and a large GPU. I was deciding between this one and the Lian Li 011D Mini.

I have to admit, I really wanted the Lian Li, because of the extra room, build quality, and aesthetics, but it had a couple of drawback. The buttons and ports are on the top, it's a little wider, and it has a lot of glass, so I was afraid of hitting it with my foot and shattering a panel. Also, the Lian Li was more than 2x as expensive, and I feel like a case is one area where I can cut corners a bit. Also, although it looks pretty, I'm not planning to install a bunch of LED lights, and I'm keeping it under my desk anyway, so it's not really a showpiece.

I would say that this case, the Cooler Master, so far has met my expectations.
Pros:
The build quality is decent. I didn't run into any sharp edges or poorly-cut panels.
The looks are understated and minimalist, which I like.
Space is well-used and well designed, so you can fit a lot into a smaller space.
Shorter tower.
Buttons and ports on the side.
I/O panel can be placed in many positions.
Can be positioned vertically or horizontally.
I really like the little carriers for the drives. They will each hold 1 HDD or 2 SDD (or 2 small HDD). It's easy to take them off, so you don't need to remove the screws from the drive every time you need to get access to something or if you want to move the drives around.

Cons:
The space is a little tight, and it's hard to reach all of the MoBo screws, but it's a smaller case, so that's to be expected.
The instructions are basically useless, but you can pretty much figure everything out.
The PSU is in a strange spot, and you lose access to the main power switch if you have one.
I'm not sure why the PSU is in a little carrier, but I'm glad they included an extension cord, and you can always unplug it from the outside, since there is no main power cutoff switch.
Acrylic panel isn't as nice as glass, but it's cheaper and won't shatter.
The I/O panel has a flimsy attachment to the case, so it bends a bit when you plug in a USB

Overall, fit, finish, build quality and features make this a good buy at this price point.

5.0 out of 5 stars Don't let the size fool you. This is the most pleasant case I've ever built in.
Reviewed in the United States 🇺🇸 on August 13, 2022
Color: Q500LStyle: ATX MBVerified Purchase
I bought this case because it's relatively small and supports full sized ATX motherboards. Despite the size, this case is actually more pleasant to build in than most full sized cases. The bottom line is that Cooler Master did a fantastic job designing this case. Every step of the build process has been considered and it results in a friction-free experience. In fact, the size optimized power supply layout makes the power connections far easier to plug in than standard cases! The fit and finish is also really good. There are no idiotic brackets scratching you as you bend over trying to plug in a cable. There are no sharp corners to give you cuts. The IO panel can be removed during building and replaced after you find extra space in the case and have it plugged in properly. There are cable cutouts everywhere you need them, and some places where you never knew you needed them! The only significant limitation I notice is that fitting a radiator in this case may be frustrating or nearly impossible. However, don't let that stop you. This case can fit very large CPU and GPU parts inside it which is really shocking considering the size. I got rid of my Phanteks and I won't miss it. This is designed so much better. Cooler Master really hit a home run with this case layout and I hope they continue to make more cases with this compact design which is actually superior to a standard ATX mid tower.

I do suggest you invest in an intake fan for the front to maximize airflow.

4.0 out of 5 stars Case could be improved in some aspects
Reviewed in the United States 🇺🇸 on September 14, 2022
Color: Q500LStyle: ATX MBVerified Purchase
The cable management of the system could be improved, and the psu holster is bare bones as possible. There is a LOT of autonomy in positioning of almost everything other than the mother board and it’s components, so if you don’t like self-direction on psu and fan placement, then this case probably isn’t for you. I needed a compact space for the PC because its going into an RV, otherwise I likely would not get a case like this one. I’m not a huge fan of the way the SSDs/HHDs are equipped in this system. It works, but could have been better implemented. A lot of shortcuts were taken with this case. However, it is a very budget case, so you get what you pay for, and in that respect, you get a little more. So, price to quality is a positive here despite my criticisms.

5.0 out of 5 stars Amazing Case For an Amazing Price! (Model: Q300L)
Reviewed in the United States 🇺🇸 on June 25, 2020
Color: BlackStyle: Micro-ATX MBVerified Purchase
So first I'd like to state that this review is specifically for the Q300L model. Amazon does this annoying thing where they mix all the reviews of all the models together and I can't stand it so I'm just stating the model flat out.

I just built my 10 year old nephew’s PC using this case and I have to say that I was very surprised at how much I loved building in this case. Originally I bought the Compucase HEC HX300 case for 30$ from Newegg and I was just frustrated at the lack of air flow from that case. It only had room for one fan which was the back exhaust and that's it. It didn't even have holes for the power supply's intake fan! It was my fault for not researching enough and buying something so cheap. Then I did a little research and came across this case. It is only 50$ but has everything I want. I've seen PC builders on youtube build with this case and they all had great things to say.

So the first thing I like about this case is obviously how much airflow it allows. It's an interesting design because there are holes all over the top, all over the bottom, and all over the front and you can install 4 fans if you wanted to (2 up top, 2 in front, 2 in bottom) in addition to the included exhaust fan at the back making it support up to 5 fans! Now with all those holes you might be thinking this is going to be an ugly case but as you'll see in the pictures this is not the case (pun intended) and it has very sleek looking dust filters to cover the top, front, and it’s not obvious from the picture but it has a filter on the bottom as well. I was pleasantly surprised to see that the filter is magnetic which made removing them to install my fans a breeze (pun intended). I also imagine cleaning them when they get dirty will also be very simple. You can simple remove them and just rinse with water. One tip when installing fans is that since there’s air holes all over, they actually made a very small indentation around the holes that you should screw in your fans. These “guides” are hard to notice but if you look closely you’ll see them. They have space for 140mm and 120mm fans depending on whatever you want. Air is able to easily flow through the filter so my air flow issues were resolved!

The case also looks very nice in my opinion. I have the black model just because that’s what my nephew wanted but in review videos I’ve seen, the white one looks very nice as well. Cable management at the back is pretty good too and the case comes with a lot of zip ties. The filters I mention above are also very aesthetically pleasing. The power button, 2 USB ports, headphone jack, and speaker jack are on the side which I don’t mind. The interesting thing is that this IO panel can be unscrewed and moved to the other side which is nice. The clear side panel is acrylic but it’s a 50$ case so it’s fine. It doesn’t look bad at all. There’s also room in the cable management area for a 3.5” hard drive and 2 SSD’s inside the main area which is very good.

Overall the case was pretty simple to build in. It’s designed very well to maximize airflow while looking great. I think this is an excellent case especially for the price. If you’re in the market for a cheap but good PC case, then you my friends have stumbled on a cheap but GREAT PC case. I would highly recommend this case and am willing to do even more expensive builds with this case in the future.

One final note I’ll add, I built my nephew’s pc with a Ryzen 5 1600 processor and RX 480 gpu reference model targeting 1080p gaming and the heat in my old case with that one exhaust fan was reaching around 87 degrees C. After I added two intake fans in the front and one exhaust fan in the top along with the back exhaust fan that comes with this case my temperatures went down into the mid 70’s while gaming which is great. If you want looks as well as functionality for a great price, go with this case.

5.0 out of 5 stars Nice little case for big motherboards and GPUs
Reviewed in the United States 🇺🇸 on September 6, 2022
Color: Q500LStyle: ATX MBVerified Purchase
This case works well even for full-sized motherboads and GPUs. Upgraded it with 4 RGB fans: one front, one back, two on top, put Gigabyte X570 Aorus Ultra with MSI NVidia RTX 3080 ti, AMD Ryzen 7 5800X. Even with a huge Noctua fan - everything fits and the build looks decent. Airflow with extra fans is superb. The system runs cool, quiet and smooth, no thermal throttling. Front and top are basically all open surface covered by magnetic air filters. Nice aesthetically pleasing case. Would recommend highly to anyone, but consider installing extra fans. I think just one fan coming with it would've not been exactly enough.

4.0 out of 5 stars Q300L: Great for a small build, but the dust covers could be better finished
Reviewed in the United States 🇺🇸 on January 31, 2020
Color: BlackStyle: Micro-ATX MBVerified Purchase
I got the Q300L for a budget Linux build. I needed something compact and attractive, but that would have good airflow, sensible cable management options, and room for a standard sized video card if I choose to add one later. I’ve had many CoolerMaster cases before - they make great products in the entry-level price range, and this is no exception (well, mostly...see my Cons).

Pros:
- Overall this was a joy to build in. Lots of spots for cable tie downs (several zip ties are included), passthroughs with clean, rolled edges, etc. There was more than enough space behind the motherboard tray to route cables, which I don’t often find in micro-ATX cases. This turned out to be the cleanest small build I’ve done from a cable management perspective.
- Fits a 140mm fan in front, which in conjunction with the preinstalled 120mm rear fan, is great for setting up a simple positive pressure airflow. Note that I’ve added a 140 fan in my pics; it didn’t come with the case.
- Tons of space for radiators, should one want to build a small watercooled system, which I might do at some point.
- Both doors use thumbscrews, making access to the back super easy for cable routing (opening the back is also required if you want to mount a 3.5” hdd using their funky mounting mechanism - see cons for more).
- If you wanted to use this in a traditional horizontal desktop orientation, the side door has little rubber feet on the thumbscrews, but these pop off if you place it vertically, and don’t want little rubber feet sticking out the side of your case. Nice little touch.
- I didn’t think I wanted a glass or acrylic door, as I’m not really into the RGB thing, but I bought some good RAM on sale that happens to have RGB lighting, and it looks great in this case. The acrylic door is nicely tinted and seems sturdy; they’ve even installed little rubber grommets to prevent the thumbscrews from scratching the acrylic. Sweet.
- The option to move the IO panel to the top of bottom is a novel feature, but in the end I left it where it was because I forgot to switch it to the top before I started building. It may be possible to reroute the IO cables without much rearranging, but it seemed too much of a hassle after everything was screwed down. Oh well.

Cons:
- The dust filters...I really wish they’d used magnets around the edges and inside the borders of the case to ensure the dust filters lined up neatly and stayed in place. A firm nudge will send the filter askew, which triggers a bit of OCD I never knew I had.
- Also, the dust filters could be better finished - the edges have almost a serrated feel in certain spots, and in fact even drew a little blood when I raked my knuckles across the edge by accident. I might take an emery board and address this issue myself, but CoolerMaster should have beveled or rounded the edges better.
- The method to mount a 3.5” hdd is a bit awkward. There’s so much space in the front of this case, I wish they’d have included a more flexible way of mounting it, instead of tucked away behind the motherboard. I’m not using a 3.5” drive at the moment but if I do add one, it would be nice to not have to open both sides and fiddle with a weird mounting clamp.
- Uses popout type PCIe slot covers instead of a screw-in type. Expected in this price range, but always a bit of a bummer if you remove PCIe cards later. If you do end up popping one out but don’t need the slot later on, there are aftermarket screw-in covers for pretty cheap.

Overall I’m quite pleased, but also a little disappointed that CoolerMaster didn’t put the same attention to detail into the dust filters as they did into the general case layout, door mount, and cable management options. I struggled with whether to dock a star for something that isn’t a functional problem per se, but my skinned knuckles won out in the end.

5.0 out of 5 stars Stock config is warm inside, but easily fixed!
Reviewed in the United States 🇺🇸 on March 25, 2022
Color: Q500LStyle: ATX MBVerified Purchase
The case is very strong and well built. No sharp corners or edges anywhere and everything is very well laid out for such a tiny case. I went from a Rosewell Full Tower (nearly 36" x 36"x 10"), the biggest case I could find at the time, for a Threadripper build nearly 5 years ago. This Q500L case literally fits inside the old case.

The only two real problems with this case the power supply (with a full ATX board) mounts in the upper front of case and blocks air flow to the CPU cooler. Only way to solve this would be an external power supply or a fan above the power supply. Also, the mesh holes for the case could have been bigger to allow more air flow, at least where you would mount fans.

I installed a AMD 1950x Threadripper, ASROCK x399 full ATX MoBo inside the Q500L case, with a BeQuit Dark Rock Pro TR4 cooler, Cooler Master MWE Gold 850 V2 and Sapphire Rx 6700xt (dual fan) Video Card. Everything FITS!!! (accept the front cover does NOT fit with Dark Rock Pro TR4 cooler).

I like to do radical case mods, so this one is a work in progress... JayzTwoCents style, cutting holes and and modding. So far, I've only done custom snake skin paint job.

Front cover will be replaced with something meshed for improved air flow. I also have ordered some custom video card power supply cables, the current ones work but look like crap.

This is a work in progress... It runs very well with one rear exhaust fan, one front intake fan, one exhaust fan under GPU (blowing down or out side cover) and one exhaust fan above cpu/power supply. Cutting out holes for all fans would also improve air flow.

As I stated before, the biggest draw back of this build is the power supply blocking air flow. An cpu AIO could be a possibility, but I really wanted to go air.

This would be a great case for small form factor build, something with an APU or someone like me that likes to MOD and do something different.

5.0 out of 5 stars Stock config is warm inside, but easily fixed!

The case is very strong and well built. No sharp corners or edges anywhere and everything is very well laid out for such a tiny case.

3.0 out of 5 stars annoying to build in
Reviewed in the United States 🇺🇸 on June 26, 2020
Color: Q500LStyle: ATX MBVerified Purchase
if you're considering the q300/500, you're probably looking more for form factor than anything.
this case is pretty compact. putting my atx board inside of here straight in was touching the walls.
everything else is either not interesting or annoying.
so the selling point of this case is you can move the front panel headers and mount your psu in any which way.
i decided not to mess with anything because just getting the psu in this thing was hell.
there's a rather thick power supply extension cable that allows you to mount this harness along a side of the case. it was incredibly hard to figure out where the psu went, with what orientation, and how the hell to get the thing screwed back in.
not to mention because there's an extension cord, you can't flip the switch. so make sure your psu is "on" all the time. i usually flip my power switch every time i do an upgrade or have to unplug everything, so this kind of irks me since i won't be able to do that with this computer.
needless to say, most of my screws are missing some paint.
the next effort was getting the motherboard in. the i/o shield i have is fairly warped, so i can't put too much blame on the case. but i can say the cutout for the shield wasn't the most intuitive design. you may have some trouble getting older i/o shields to stay put and fit in without punching themselves out. the new reinforced i/o shields might fare a bit better.
after all of this was done, i could finally channel cables.
this was a bit easier, but dang this case has tight holes. and there's not many places for the cables to come out of, either.
so there's kind of a rat's nest coming from the psu and front panel headers, and they all come out of these small holes punched into the corners with shrouded channels. these also aren't the greatest and don't exactly hide everything going on behind them. my usb 3 header might as well have had its own hole instead of this mess.
installing the ssd was its own hell as well. there are these 2 plates with 1hdd or 2 ssd mounting holes and you remove the plate to install the ssd.
the problem is if you plan on hiding your cables and using those nice channels, you're screwed because the plate is too close to the wall. so now you have a nest of cables where you installed your ssds and sata cables.
and somehow the last issue was the case fan. my board is an old gigabyte am3+ board, so it doesn't have fan headers dotted all over it. and you'd think a fan with such a short cable would at least have an extension or something so it's not running over the top of the board. most cases come with a long fan cable because its meant to go back into the corner and come out wherever the header is.
no. i couldn't stretch it over my ram to fit into one fan spot, the other would run over the pcie slot, so i ended up finding a third fan slot and routing the cable under the back of the gpu.
the fan itself is pretty cheap, too. little glossy plastic thing.
installing the gpu meant i had to route this chunky pcie cable through a hole right next to the gpu. that's fine, i'm used to that. but since that hole is right next to the psu channel, it looks like a big nest of cables going in and out.
so now that everything was done, i turned the pc on and got to the logon screen (i was just moving cases, not making a new build. so this really shouldn't have taken as long as it did)
i put back on the side panels and managed the cables a bit, and there's a nice window which i knew i couldn't really use because this computer is old and there's no lighting on any of the parts.
so of course cooler master didn't include any leds. so i have a nice dark tinted window that i can't really see into without shining a flashlight on it. it's a cute looking build on the inside. but i'm not going to buy an led strip just to see inside the window.

overall, this thing is kind of a hunk of junk and hell to build in. but once its done you don't really have to do anything. so if you're willing to wrestle with it, it'll be a cute desk pc.
