For the price it cannot be beaten
Nice case, well build, lots of space for big GPU and it looks great.

Better than expected!
I expected this case to be pretty good but it turned out to be really good. Easy to build in, many cooling options, good cable management, good airflow. It's a bit wider than I expected, but the upside is that it has an offset top mount for fans and radiators so there's better clearance from the motherboard. The tempered glass side panel looks gorgeous too. My only complaint would be that there's only two USB ports on the front compared to four from my previous case but at least they're both 3.0.

Excellent For Price
Easy use and lowered my CPU & GPU temperatures about 10° C. Very good airflow - I use it with 6 12cm fans - 3 at the front, 1 at the rear and two at the top rear. So 3 in, 3 out. Using all standard Antec and Coolermaster fans (not RGB) as I don't go for the disco look. I bought this as I had to move my PC hobby room from the coldest room in the house to the warmest and it does a very good job. I've not been able to test it in the 30-40°C temps we had last summer, but a drop of ten degrees now will most likely translate to several degrees in summer, which was my aim. I also have th option to switch to water cooling with this case. The only thing I didn't like was that there is not enough room left for the standard power cables that you tend to get with modern motherboards. The SATA power plus are thing, but they are quite long, and tend to stick out from the SSD positions, so this was the main issue with fitting my PC into the case. It also was the cause of a couple of my 4 SSDs not working and having to rearrange everything a couple of times - this is why it dropped a star. The PSU can be a bit tight getting in and out, but wasn't a big problem (Corsair RM850x) even with all the cables attached - just have to be careful. There is also plenty of space for my RTX 2080Ti and I aim to buy the upcoming RTX 4080/16 and have measured the case - it should fit without issue. At this price, it's definitely recommended.

Quite cool
Its cool, needed it because the PSU I bought was too big for my old Tower You can have water cooling in it.. or just 5 fans (Im using 5 fans)

OK but suffers from "aggressive cost cutting syndrome"
It wasn't fun building in this case. Holes for the motherboard standoffs aren't threaded so you need to force screws in with a provided "tool". One of the holes was too large and it stripped with minimal force. Incidentally it was on the upper side, where support for a heavy air cooler is crucial . All accessories including the single 12cm fan (1000rpm btw), feel cheap. The motherboard tray and the sheet metal at the back have moderate flex. The transparent side panel is acrylic and the front panel section feels quite flimsy. Clearance in front of PSU is minimal, drive cage not removable to mitigate that for larger PSUs. No room at the top (above CPU area position) for 14cm fans - clashes with the 8pin. On the positive side: the overall construction is solid considering how light it is. It looks pretty good without RGB, understated and much less "gamer" than in the photos. It has rubberised supports for the PSU. It can mount 4 SSDs + 1 spinner with the provided kit. It has very good forward clearance for long GPUs. Airflow is very good - excellent temps with the right fans and placement. Easy cable management.

Cooler master mb511
The case does look pretty nice. It was easy to install the stuff in it an cable management is ok and easy but is more space for better. I like the airflow of the case. I installed 3 argb fans on front and one on the back ( the case came with it ) and it is wow. The gpu in full load is averaging 54-61°C and the cpu because of the stock cooler is getting 61-71°C ( ryzen 5 3600XT) I do like the case and I hope I'll install soon 3 more rgb fans on it.

Cool master gaming case.
Nice case for a gaming pc, plenty of room inside for several fans. Cables hidden behind motherboard. Only fault is there is nowhere to fit a cd/dvd drive, I know a lot of people download games but I still have a lot of disc games.

Perfect size
Fits components well, durables plastic and metal Material, no lighting but that’s fine, promotes great cable management as it makes it easy. doesn’t reduce Noise from fans that well but it’s okay .

I have purchased this cause a few times for pc's that I built for other people. Mostly due to the price. The side window is not glass which I prefer. Putting fans in the front can be a pain due to areas that are hard to reach but its workable from inside case with very long screwdriver. It doesn't look bad after complete build. My last case was used. I didn't order used. The accessories were missing Screws, stand offs, etc. I know whats missing because I bought the case 2 previous times, and this usually is in a small box sitting in HDD area. Taking off front panel where fans go was scratched. The case was great the first 2x but used and missing parts I don't like.

Hasn't broken down in two years of service. It offers a lot of space to fit the graphics card, and is quite easy to clean as well.

Best gaming case!!!

Tem um ótimo espaço atrás para comportar todos os demais cabos da fonte. Tem vários furos para passar os cabos de modo que fiquem bem organizados. Não teve nenhum problema com a conexão USB frontal ou mesmo do áudio. Os botões de desligar e reset funcionam perfeitamente. Para retirar a parte da frente tem que forçar com uma chave de fenda. Coube muito bem um WaterCooler de 360mm na parte frontal e duas fans na parte superior. Na parte de baixo também tem um filtro para evitar que muita poeira entre na fonte. Excelente e espaçoso gabinete, gostei muito.

Ja tenho esse gabinete ha mais de um ano e não tive problema. Coube bem todas as peças e os filtros são de grande ajuda pra poeira. Fiz a limpeza anual e não havia muito pó internamente.
