Perfect All-arounder!
Super easy to build in. Small, but spacious enough to accommodate most tower coolers and GPUs. Cable management is alright. Also, the glass is actual tempered glass now, so it's build quality feels more premium now (compared to the previous version). I upgraded my son's PC and needed better airflow as the previous case he had was not cutting it. After the swap, the PC looks miles better..airflow improved significantly (fans no longer on full blast constantly). Would definitely purchase again. PS to cooler master- You should make custom magnetic dust filters with graphics or patterns 👀

Excellent product and deal!
Really don't understand why this case gets some negative reviews. IT'S PRACTICALLY PERFECT in its design. I have the build finished and its a nice tight build with great airflow. I bought good fans... and calibrated them. I then hardwired in the fan that came with the case down low beside the PSU and the airflow is excellent. The porous case is genius, and the metal mesh filters magnetic are genius. Practicality matters this is a great case. The thin metal tin for the back should be a little thicker but it installed easily and works great. Maybe one more USB c on front? Price point is perfect you can't get a better deal! Glass wall is now the top surface you can set this up like other cases or lay it down on its side... bigger supports four on bottom maybe a little bigger? Excellent product and deal!

Great Case at This Price Point
I know this case divides opinions but I am a big fan. I like the relatively simple look of it. The pattern of circles shown in the main photo for the item is actually a pattern on the mesh sheet; underneath, the metal itself has many small holes. The case is pretty difficult to work in as the glass panel is your only real access point, but it was entirely manageable. I had to bend the rear GPU bracket back just a bit to accommodate my RX6600XT, but no big deal there either. The rear channel for cable management is a great addition, and the case itself has a nice paint/build quality. The thermals for this case are excellent. Under worst stress conditions, I have not gotten anywhere close to thermal limits. HOWEVER: Note that a 240mm AIO will NOT fit on the top of the case; with the motherboard installed, the RAM will interfere with the AIO. I was able to install mine at the front of the case (make sure you do this with the radiator tube side down), but keep in mind that the thickness of your AIO will then cut into your CPU clearance. Generally, AIOs are around 50mm thick, so the 360mm GPU space becomes more like 310mm. Also, bear in mind that the case only comes with 1 fan, but fans are cheap so this is not a big deal. I installed two 120mm fans on the top of the case, kept the single fan on the rear, and installed one 120m fan on the bottom next to the power supply. This makes for excellent airflow, and the removable mesh panels make it very easy to manage dust. Can't beat this case for the price!

Great overall case! Questionable airflow choices
Overall? An excellent budget-friendly case that has everything you need with a very clean-looking design and compact size. I do have some nitpicky things regarding airflow but for budget-midrange builds this is perfect for a case under $60. Pros: Clean aesthetic with 2 magnetic dust filters. Easy to build in and the lack of psu shroud allows for more air to circulate. Front IO is more than enough for budget in mind. Can support a 240mm aio in front if desired. Clean cutouts for cable management despite compact design. Cons: Airflow is questionable. The dust filters have a hole printout design that makes the case look as if it has larger holes for airflow, but the actual holes behind the filter are significantly smaller. This caused temperatures to get higher than expected. For reference, I used an RX 6600 and an R5 5600 with a stock cooler. With 2 140mm fans in the front and 120 in the back for exhaust as well as a stock CPU cooler, my temps were reaching 80 degrees under load. After getting a cheap aftermarket cooler and adding 2 extra fans on top and bottom for intake, temps for GPU and CPU dropped to around 70 under load. After some tinkering with fan curves, I got an optimal fan noise to temperature ratio. If the holes on the actual case were the size of the dust filters, then I would have not needed to buy 2 extra fans and a tower cooler, luckily I had some budget to spare. Coolermaster, if you do a refresh of this case, please address airflow issues on the front intake panel. Doing so would make this, in my eyes the BEST budget case in the market. All in all, I highly recommend this case, especially if you're on a budget. Just don't expect a 4090 and a 14th gen i9 to breathe here.

Compact case
This is an excellent overall case for low budget, plenty of space for a MiniATX mother card and a RTX 5080. I only have 2 intake at the front, and 1 outtake fan on the back and temperatures are super low. 66 max for the GPU and 58 max for de CPU (Ryzen7 7700x).The easy removal of the both panels is good. And this new version coming with tempered glass!

Best MATX Case for the money
It's an improvement, however slight, over the original Q300L. And the original Q300L was an amazing case already. It's easy to build in, $40, and well built. Form follows function on this one and if you don't need every gadget known to man, it's great. Good cable routing options as well. Just a really great case. Always recommended.

Excellent price on sale.
Fantastic case. This case was used in the first build with our teenager. I can absolutely say it was a hit. Nothing to difficult. Good materials. Clean design.

Great case, nice and small, but just big enough to support a 5070ti. There is a lot of space in the back for someone like myself that just likes to stuff the rats nest in the back and close it up.

Producto de calidad, el gabinete llegó con su embalaje completo, bien protegido, tiene buenos materiales de construcción, buen espacio para la gestión de cables, le caben tarjetas de video hasta 35 cm de largo, torres de disipador hasta 16 cm, y ventiladores de 140 mm y 120 mm, si compran este gabinete Cooler Master Q300L V2 valdrá la pena cada centavo.

Anteriormente, eu usava um Cooler Master Q300L. O Q300L V2 é, praticamente, o mesmo modelo (porém, com a tampa lateral em vidro temperado e conexão USB-C). O ruído das ventoinhas diminuiu graças a essa tampa, além de não arranhar como o acrílico. Gabinete compacto, bonito, ótimo air flow, com espaço interno legal para a instalação de ventoinhas/WC's e vêm com filtros de poeira magnéticos de fácil retirada/instalação. Sinto falta do botão de RESET no painel frontal. Apesar disso, estou satisfeito!

It's one of the few cases where you can fit big components in to a mini build. Lots of room on the inside, lots of build possibilities. The case is bare bones but it's great.
