The case, in all comparisons for the best air flow, is in the TOP 5. Attention: Not the one with tempered glass, but with MESH. It has three high-quality fans at the front that do the job satisfactorily.
On the top, it has a magnetic mesh for ventilation and space for 240 and 280 liquid cooling.
Inside, an MSI 450 A-PRO MAX motherboard was installed with a Ryzen 3300X. A BE QUIET PURE LOOP 240 liquid cooling was installed. Idle temperatures are 35-40 degrees, and in gaming, it never exceeded 50 degrees. In a 100% usage stress test, the maximum reached 68 degrees.
Now let's move on to the negatives. The RGB controller is inside the case, and when you want to change the color, you will have to open the side glass. While it has a high-quality magnetic mesh on top, at the bottom, where the power supply fan is located, it has a simple mesh that catches on protrusions. Of course, it is not visible. The glass is quite good, but it only has screws on the top, while at the bottom, it simply hooks onto a slot. Not that it has any problem, but it gives you a feeling of insecurity since the two screws don't seem to hold very well.
Overall, it is one of the best gaming cases in its category. After that, you would have to go for Be Quiet or LIAN LI, which start from €150 and above.
