This is my first PC case, and I am genuinely impressed. The airflow is excellent, the build quality is solid, and the design is exactly what I prefer — clean, strict, and professional looking. If you are into flashy RGB builds, this may not showcase lighting as brightly as lighter-colored cases. However, if you prefer a stealth, minimal aesthetic with strong airflow and good value, this case is an excellent choice. For its price, it is hard to complain.
Excellent price-to-performance ratio
Very good airflow and ventilation
Clean, minimalistic and strict design
Spacious interior — plenty of room for cables and components
Solid material quality for its price category
Easy building experience overall
Installing bottom fans requires removing the lower panel, which is secured with star/Torx screws — not very convenient if you don’t have the proper tool
If you plan to use RGB fans, the fully black interior absorbs a lot of light, so the lighting effect is not very visible

I am very satisfied with the product, although it is bigger than I expected and it does not fit in the foch I have on my PC, the hold will have to be on the table and I have a reason to admire not only the case itself, but also my assembly through the side glass
good price ratio: power
transparent sidewall (which screws on as a sidewall)
3 built (140 mm! ) large space fans allow good airflow and are quiet
space for handling and hiding cables
connectivity (even usb-c, not thunderbolt)
nicely visually processed
more than enough slots for SSD drives
minimalist packaging with everything you need inside
larger than I expected (my mistake, I didn't check the external parameters, but the internal ones)
a bit worse handling of the HDD slot, especially around the cables from the PSU
for my taste there could be more HDD slots, but for today 2 is probably enough
without dust filters (but one is at the source)
the cabinet had accessories inside, including the manual, and I had to open it to find everything (5 minutes of stress after opening the box from the fact that only the cabinet without accessories arrived in the package)

Excellent Price
3x140mm free fans
Excellent air flow
280mm AIO was a tight fit on top. A thick radiator might be a problem with some motherboards.
E-ATX mobo covered the side gromets and had to route the cables from top and bottom.

price
little space for water cooling 360mm
Magnetic strainer rises when using the screws to hold the coolant
