    Perfect, but be careful with the size.

    Very good case, but pay close attention to the size of the graphics card. The 5080 fits, but I'm not sure about larger ones. Otherwise, it's a great, practical case.

    PC Tower

    This PC tower is incredibly beautiful! I fell for it and I don't regret it! I chose all my setup inside with a great LDLC advisor on the phone! He understood what I wanted and he made me a setup that was just right and at the same time really beautiful!
    Very satisfied with my order! And with this tower, the air circulates really well inside, so I put it on a stand with wheels to make it easier to move!

    Very good hobble

    When I got it, what really stood out for me was its adaptability, its many features to manage the way you want to build your PC, and that's something that other PC cases don't think about, this case has a lot of space if you want to put a big GPU and the fans are really quiet.

    Spacious and practical

    I chose this box for its airflow and practicality: 10/10. The space at the back is deep enough for a neat management cable.
    There's a small fans/argb HUB at the top to simplify connection of the multiple fans.
    The overall look is sober (you can, of course, adjust the RGB as you wish).
