I have the above case for about 6 months and overall I am satisfied. It looks very nice. I was disappointed when I found out (after the purchase) that it has one of the worst airflows among cases in 2019 (tested by "gamers nexus" on YouTube). The reason is that even though it has holes everywhere and seems to have good airflow, each side ends up being 70% metal and 30% holes because there is a large distance between the holes. Until then, I hadn't noticed any temperature issues, but afterwards, I realized that there is indeed a small problem. I have a Ryzen 5 3600 and an MSI RX 580. Initially, the temperatures were 70+ degrees Celsius for the CPU and 75+ degrees Celsius for the GPU under load, and the stock AMD cooler was struggling.
So, I bought some 140mm fans for the case, which I recommend everyone to buy and include in their budget (or 120mm), and a CPU cooler (optional). On the case's website, CoolerMaster says that it doesn't support 140mm fans in the front and bottom, but there are holes for:
Top: 2x 140/120 mm
Bottom: 1x 140/120mm + PSU | 2x 140/120mm
Front: 1x 140/120mm + PSU | 2x 140/120mm
Rear: 1x 120mm
The PSU can be installed either at the bottom or on the right-top, and depending on that, there is space for 1 or 2 fans.
⚠ If you install the PSU at the bottom, the entire ATX motherboard won't fit. For ATX, the PSU must be installed on the right-top.
It comes with one 120mm fan at the back, of average quality.
⚠ On the bottom side, even though it has holes, if you install a 140mm fan, it may "hit" and you won't be able to screw it in (at least my fan, which is 27mm in height). I recommend using a 120mm or slim 140mm fan for the bottom.
edit: in the photos, it seems that it barely doesn't touch the front panel connector, but it hits the bottom part of the motherboard, so it can't fit below the motherboard and there is a small overlap. The 120mm fan doesn't screw in below the motherboard but in the front, so it won't have any issues.
⚠ Since the case has holes everywhere for airflow, you can tie the cables with zip ties to them (they don't fit perfectly) a bit to the side, and you won't be bothered by the holes. That's what I did. Also, it can fit a 140mm fan in the front, even though it's not mentioned on the website, but be careful if your PSU is long, like the Corsair HX Series HX1200, the 140mm fan may not fit.
As for cable management, it's generally a difficult case, but it has a lot of space at the back. There are many points to hide cables and route them to the back, so you can have a visually pleasing result. For me, it was the most challenging cable management I've done, but it turned out very nice.
The PSU mount is also a bit strange. Don't confuse the screws because some are small and go through the inside. When I switched from a full wired to a semi-modular PSU, because the cables would be somewhat visible, with a semi-modular PSU, the result is much nicer visually.
The front panel can be mounted in 3 positions: top, right, and bottom.
⚠ If someone wants to mount the front panel from the top and pull the USB3 to the bottom side of the motherboard (where the connector often is), the cable won't reach to pass it behind the motherboard and below. You will need an extension or the cable shouldn't go behind and be in the middle (boo! for the last option). I recommend mounting it on the right side so that it covers the PSU cables a bit.
I saw in videos that it supposedly doesn't have good build quality. It's actually fine. It's not made of steel, but for a budget case, it's very good, and everything is in its place. The side panel is not tempered glass, which I don't like.
The PCI caps are metallic and screw-on, not glued on, which eliminates the need for breaking them.
It is not a disaster as often presented on YouTube, even without the case fans. The Ryzen 5 3600 starts throttling at 95C, and I wasn't even close to that. On my GPU, the fans didn't go above 75%, which means there was room for more. Sometimes it just made a little more noise before I installed the case fans.
edit: with an upgrade to the MSI 5600xt gaming X, which has a thick cooler, the GPU fans don't even start, and I can barely reach 70 degrees, and then they start to lower it (I haven't adjusted the fan curve).
After all this, I wouldn't recommend the case. Today, at 70 euros plus an additional 15-20 euros for fans, we reach 85-90 euros. With that money, you can definitely get a case with better airflow and tempered glass on the side, which are available within this budget.
If someone, like me, really likes the design, then go for it. It's not a disaster and it's very nice to play with.
