Nice case in terms of design.. Only downside: no possibility to add internal DVD / Blu-ray drives..
That's why I give it 4 stars / 5

The design is very nice with the three fans on the front..

Perfect
Hello,
Here is my objective review of the Cooler Master MasterBox 600 (Black) from Cooler Master.
Strengths:
The case offers a sleek, modern design that is suitable for both gaming and professional use. The ventilated front panel ensures good airflow, helping to maintain optimal temperatures. It is widely compatible, supporting large graphics cards and cooling solutions, including water cooling. The internal layout makes it easy to assemble and manage cables. Finally, it offers good value for money.
Weaknesses:
The materials are traditional and give a less premium impression. Soundproofing is limited, which can allow fan noise to pass through. Customisation options, particularly RGB, remain fairly basic.

Evolution
Hello, it's been at least 7 years since I last changed my PC and I've noticed several practical changes
Quick to switch on and off
Now you can press the button to switch off directly
Management of the video card fans, which really come on when they're needed.
So I have no regrets about my purchase

Luminous and very, very beautiful case
A very attractive, robust and high-quality case.
The fan colours look great and add a lot to the overall aesthetic.
