Cooler Master MasterBox Q300L Micro-ATX Tower, Black (MCB-Q300L-KANN-S00) & Seagate Barracuda 2TB Internal Hard Drive HDD – 3.5 Inch SATA 6Gb/s 7200 RPM 256MB Cache 3.5-Inch

***Q300P***This case sucks, and especially not air. It just sucks. I bought this case for a build, tried to cut a corner by going cheap on a case and should have just spent some extra on a better case. I love the look of it, the handles and RGB look awesome. BUT. That’s about all I like. It’s absolutely massive for a Micro ATX case, it’s wider and taller (with handles) than most ATX towers. The “hole” case design is just awful. It makes for absolutely no air movement, on top of the classic Cooler Master plastic panels that choked the air even more. Also the fans were loud not because they’re bad fans, but because the air was just hitting metal on the front. The front AIO panel had two screws that were so tight from factory they rounded off, and I couldn’t get them out. I have a fully modular PSU and cable management still wasn’t fun. The placement of your SSD is just weird as well. Just all around I hate this case. The only way I’d recommend this case is if you are constantly moving it because that’s the most well thought out and most well built thing was the handles.

Absolutely love how this case and build came together. Plenty of room for a simple build, and I love the option of moving the power/usb's around rather than them always having to stay in the same place. SSD installs are clean, love that the case doesn't have a big stack of metal in the front for HDD, but keeps the HDD hidden behind the back panel which still leaves plenty of room for extra cord. The power supply gets installed securely with a bracket in the case, and is installed a little further into the case to allow for a nice handle on the bottom backside of the case. Overall this case is WELL WORTH the small amount they are asking for. I have built with cases that cost 3x as much that don't make as much sense as this case did. Beautifully built.

I had some old parts laying around and my son wanted a gaming computer. So, I went around looking for a case to stuff all this stuff into that was nice looking and quality. He was given the following:Intel G4600Asus B250M-K8GB Corsair Vengeance LPX DDR4 2133XFX RX560 4GBWe were just using parts that were laying around and acquired from friends, so we don't have anything fancy here or any crazy RGB lighting or color schemes. Just a budget-minded micro-atx build for a budget case.The design on the dust filters is pretty nice, it's not fooling anyone and you can tell it's just a design on a filter, but it does a good job of looking the part and appearing more exquisite than it is. The dust filters cover the top, front, and the bottom of the case and are simply attached by magnets. It's so easy to pop them off and clean them, literally in seconds. It's a very refreshing change to most cases with poorly designed and hard to access dust filters.Airflow is amazing. The entire case is open on the exterior and the only thing covering the holes is the dust filters. A front mounted radiator would work great for water-cooling. You could also mount smaller radiators on the bottom or rear. In my particular case, I do not think I could get a 240 radiator to span the top without interfering with the CPU cooler, but a 120 would fit fine if positioned at the front.The USB ports on the side are a nice touch and can be positioned on any of the 4 sides of the case. The only hiccup with doing that is the wiring must follow the ports wherever they go. So, you have to plan ahead so the wiring doesn't get in your way, for instance the wiring may block the mounting of a large radiator if positioned in the front.Wiring is easy and there is plenty of room to cram your cables out of view. I'm using a non-modular PSU and I was able to hide all the unused wires just fine. There are also nice spots to mount your drives on the backside of the case.The window is tinted and a little dark. I do not have any lighting in the case yet, but it's difficult to see inside when there is not good lighting the room. I'll definitely be adding a small light bar to bring it to life. If you have RGB fans and components though you should be fine. The window is not glass and thus it scratches easily. The tinted nature makes it hard to see the scratches at viewing distance though, but that's just the nature of these windows. Unless you're gonna drop money on a glass case it's just something you have to live with.Another small little touch is you can stand the case up like you normally would, but they also included rubber feet on the back-side of the case. So, you can actually lay the case down flat if you wish and have the window facing up for everyone to view inside the case as they walk by.Honestly, I'm just really impressed for $40. It's not made of gold or anything, but it's just well designed and good quality for this price range. It's also a nice looking case that would look nice anywhere in the house, even the girlfriend or wife won't get mad if this is in the living room. I definitely plan on using it the next time I build a PC for a customer.

I was looking for something smaller and affordable to transplant my microATX system into from an old Antec 900 that provided decent air flow for my 4790k and RX 580 and I settled on the Q300L TUF edition. There is decent room in the back for cable management but I suggest going with a modular power supply to save the space that's there. I have an older Corsair CX750 that isn't modular and I am having a tough time closing the back cover completely and I don't have any room in back for my RGB controlller and all of the wiring. This is definitely a great case for the money, though. The modular structure and customization options are hard to beat with other manufacturers.

Case is decent enough put together (remember you aren't spending a ton of money on this guy). Fit a full size GTX 1080 TI and a Ryzen 7 2700x.Seen a lot of complaints about "no air-flow" and machines over-heating (even from 'professional' reviewers) and I think I've concluded they simply don't know what they are doing. If you are building ATX, your PSU is going top / front of the case. You can then fit a 140 MM fan right below it as an intake fan. 120MM exhaust comes default on the back. Two intakes on the bottom, and two exhausts on the top. System temperatures are no different than when I built in my massive full tower.So if you know what you are doing, go ahead and build in this case. If you don't...the full size and mid-towers are easily searchable on Amazon.

The case is cheaply put together. The magnet side cover is a gimmick that becomes a headache. The rubber piece that holds the filter screen easily comes off and get lost. The case gets one star because the basic of any case (both side open for easy install and easy cable management) is at least there. The fan that came with the case came broken and for something so cheap it wasn’t worth going through the hassle of trying to get a replacement fan instead I ended up using one of my older fan. This became such a headache that I ended up replacing it with something else. Maybe in the future I will end up drilling this case out and use it for something else. It’s a complete waste of money.

Having had a larger PC case for a while I thought it was time to move to a smaller option. I liked the look of the BitFenix cases but at around the £50 mark, the CoolerMaster Q300L was just what I was looking for price and design-wise.Being able to choose where the USB and power buttons are placed is a cool idea but if you want to use it at the top (like in my setup - Pic above) you will need a USB extension to run the cable down the back of the case.There's plenty of room for cable management and the build quality is good. I have a full sized HDD at the back and there's also space for two SSD's.Having all the holes means that you don't get much airflow pressure but I haven't had any heat issues with my overclocked AMD 1700X. If you're looking at having your PC on the floor, I woudn't choose this case as it'll most likely be full of dust in a few months. For desktop, I've had it running 4 months with minimal dust although you can see a slight dust ring around the front intake fan.When setting up be careful with any fluff and this will easily get stuck into magnet dust filter mesh.If you do decide to buy the CoolerMaster Q300L, you'll also need to invest in some fans as it only comes with one medium-volume fan. LED fans looks great and I've added three plus used the included fan as a front-intake.Pros✔ Cool Design✔ Build Quality + Cable Management✔ Removable Magnet Dust Filters✔ Compact SizeCons- Only One Fan Included- Perspex Window Tint Is Very Dark- USB Cables a little shortI also upgraded the CPU fan to a Arctic Freezer 7 Pro and there's plenty of horizontal room left. If you're going for a big CPU cooler, you might have to watch out with the clearance.Cheers,Jim!

Before I get to my main criticism of this case, I will list the positives:1) Very clever magnetic dust filters which double up as aesthetically attractive (but still understated) covers of the front and top.2) Beautiful smoked side window, made from polycarbonate (not glass).3) Clever option of having the case stand vertically or flat, as it has rubber screw feet on the non-windowed side panel.4) Tons of room behind the motherboard panel for cable management, making for a very tidy build indeed.Now the negatives (1 big one really):1) The location of the HD mount is behind the motherboard panel. This is an area that is TOTALLY unventilated, and so the HD gets very hot here. The bracket itself is clever, which is a plate that is screwed to the HD and then this plate clips (and secured by a thumb screw) into its mount.Because of the excessive heat build-up of the HD (obviously not helped by ZERO air-flow and heat from the back of the CPU), I decided to mount my 3.5" 2TB hybrid drive elsewhere. There's a few alternative locations for 2.5" drives, but not my bigger 3.5" HD. I re-used a mounting bracket from an old build and mounted it on the case's floor panel in front of the PSU. It stays MUCH cooler there.Overall the result is good. But I cannot fathom the hideous design choice of mounting the 3.5" HD behind the motherboard where it will bake. If you're only using 2.5" SSD/HDs then you will be fine.

Probably not the best idea ever to do a tight mATX build as my first PC build but overall went well.Word of advise be careful with the power panel, I didn't realise the panel had 4 screws holding it in the case (thought it was just the 2) and removed the top plate as it came off easily only to find that it would not go back on the same again and the power button was held on by this plate (rewired my case so that the reset button is now the power button, and positioned the power button for show).Case has managed to somehow swallow 2070 super gaming X trio but this was a very tricky install (this was why the power panel had to be removed).Cooler master ml120r argb cooler fit well too but getting the pipes in the correct position was also tricky.I have 2 mf140r as intake at the front and the original 120 fan from the case positioned at the top as exhaust near the RAM. So case is very adaptable and nothing is running too hot.Lots of room in the back for cables, do not have any HDD/sata SSD (only m.2) installed though so can't comment on cable space when these are taking up space. But do have the RGB controller from the ml120r back there running all the RGB fans. Some cables can be fiddly to run (especially the CPU power cable connecting to a MSI b450m mortar max).Overall pleased with this case, looks good and functions well.

I expected better from this case. It is actually really cheap and nasty. This is a £30 case at most, not the £60 I was robbed for it.It looks better in the pictures than it does in real life. The side panel for example is just terrible. The placement of the USB ports is in a really flimsy area and when you connect devices it has a lot of flex. Cheap Plastic meets cheap metal and what you get is just a junk product.The MESH Covers are just awful. You only need to look at them and they move out of place. Oh and if you take them off you are left looking at some pretty ugly metal work.Come on Coolermaster, what is this? Awful.The only redeeming thing was it did keep things cool but man it is just a terrible case.

Right.. If you're just going to stick SSD's in this case, then great.. Room for 2 or 3 of them.However, if you want to put a load of 3.5" drives into it, but still want a small-ish case, then beware..I wanted this case to replace a much smaller case I use as a NAS. I wanted something with a bit more room and something a bit easier to keep cool.. It's got up to 6 drives (5 of them 3.5")..Aside from the awful mount point for the single 3.5" drive**, there is NOTHING to allow you to natively add a load of 3.5" disks. So I had to create my own little HDD rack using white 30mm plastic angle sections.. I've managed to stack 5 of them on top of each other, with 1cm between each, and sit this 'enclosure' behind the front fan..A total pain in the behind, but it works....If this case were 1cm wider and 1cm longer, it would be perfect..**even the single 3.5" mount point is unsuitable as there is NO ventilation at this position..
