Overall, a good case. Quality, beautiful, and with good space. Something that particularly challenged me was the installation of the semimodular PSU. It barely fit after quite a bit of effort. Access to the PSU area should be easier! It has dust filters, but they are just magnetic that "sit" in place and can be easily removed but also accidentally.

The side glass is very good and heavy, and the width of the case is quite large, accommodating the big Arctic Freezer 36 cooler on the Ryzen 7700. I installed a short graphics card with two fans (4060ti), and it fit comfortably. I also installed 3 RGB fans of 14 (two in the front and 1 on top). The temperatures I observed on the CPU and GPU are excellent, while the whole system is quite quiet.

Very good case, I would have liked it to have better airflow because it has very little space on the right and left for air to pass through. They could make it larger because the grilles it has are thick. (With the front window, my GPU reaches 72 degrees at 100%, but as soon as I removed the window, it reached 52 degrees, so I imagine that with another case it would be somewhere around half, which is satisfactory.)

Very nice box, at a very good price.. I experienced a bit of a regression as seen in the photos. You can make it very beautiful. The RGB looks very nice, and the cable management is satisfactory. I don't see a reason to buy something more expensive.. I bought it for 55 euros.. super... I recommend it. Also... it comes with a manual.
...after some time, I want to mention the air flow. The air intake is quite mediocre. By removing the glass front and letting the fans draw in enough air, I saw the temperature drop by 3 to 5 degrees. Also, the good news is that I recently installed my new Gigabyte 4070 s card, with three fans, and it fit comfortably.

That the best thing I have bought, tinted glass on the side, silent fan and all the cables fit on the back side as well as the power supply, you don't see anything. Spacious, mesh with magnet on the top and bottom side. Easily comparable to a case worth 100 euros or more.

The case is very good! Very beautiful, spacious, dust filters, cover for the power supply, and quality construction! Even for a beginner like me, you can easily build a computer with the Matrexx 50. I highly recommend it to anyone who wants to upgrade an old computer with an old case or build a new computer. It's worth the money it costs! Please note that: 1) It only has 1 fan at the back of the case. (You have many options and can buy good ones for 5 euros!) 2) The package does not include a manual.

Very good case. I thought for its price it would be plastic and not glass, but it is completely clear glass with tinted black. Good cable management and very spacious for its size. It's worth it for so little money and more.
After 2 years, I finally changed the graphics card and processor, but unfortunately I noticed that the airflow is bad, to the point where the computer shut down due to high temperature.

Guys, just don't think about it, it's the best case.
positives
1 spacious and you can do good cable management
2 good airflow
3 you can add 3 120mm fans, 2 on top and 1 on the back

The box has a sturdy, heavy construction, which is due to the fact that the side glass is glass and not plastic. The front panel is a bit difficult to remove (meaning you might think you'll break it but it doesn't break), plenty of space especially with a micro-ATX motherboard. Cable management is an issue, especially if you have a non-modular power supply, so the cables need some "squeezing" to close the back panel, but if you manage to do it, it doesn't bend or show anything. It comes with screws and ties to properly organize, in case you're missing anything, at less than $50 that I bought it, I consider it a very good purchase.

Very good construction, I believe it is the best value for money, meaning around 50 euros that I bought it for.

Beautiful. High-quality construction with glass on the side and front.
The new version features a PSU shroud and better cable management.
