The case is not without its drawbacks, but it’s good, especially for the money (I bought it for 5500)

Good mini-tower for a quiet build
Quite thick steel
Huge height clearance for the CPU cooler
Excellent included fans (although I replaced them with my own Noctua)
Stylish design
Plenty of space for cable management on the back side
Good assembly variability: removable HDD cage, drive cage, and interchangeable top cover (choice between additional fans and a solid quiet cover)
Good set with dampeners for HDD and lots of nice little extras
Dampeners and other silence enhancing tricks work. Now I can leave the computer on overnight - the micro-ventilation in the window is much louder ;)
The drive/fan controller cage is difficult to remove. The glass panel has some play at the bottom (doesn't fit snugly into the slots). Assembly difficulty: SSD needs to be installed before the motherboard and power supply, routing wires underneath for power buttons, audio jack, and USB after motherboard installation is a non-trivial task. The dust filters could have been made better - the front mesh is quite coarse, and the power supply filter is like a Deepcool filter for 2,000.

good model, like it

It is a great combination of silence and functionality. It is made of high-quality materials, and its noise isolation really works, even under heavy loads, the noise from the system is almost imperceptible. The glass side panel allows you to appreciate the internal design of the computer, and the minimalist design adds elegance. The spaciousness of the case allows you to install powerful cooling without any problems, and it has a convenient organization of cables that helps to keep order inside. Overall, this case is ideal for those who want to balance performance and silence in one. But it is worth considering that it can be a bit heavy, and the ventilation is not too aggressive, which may be a limitation for some users.
