    Very good

    Item meets the requirements. Plenty of room to fit the equipment. The ventilation of the case is very well thought out. Can accommodate watercooling. Think to reserve a big place to him all the same.

    Not clean

    I bought this case for my son as I already have one of the brand for myself.
    I bought this box for my son as I already have one of this brand for myself. The box itself is very good and would have deserved 5 stars, but I withdraw 2 stars for 2 defects:
    -The power supply rests on 4 studs with dampers, but on the box I received there are only 3 dampers, so on one point of support, the power supply rests on nothing.

    The power supply rests on 4 pads with shock absorbers, but on the case I received there are only 3 shock absorbers, so on one point the power supply does not rest on anything. -In the case there are 8 flexible pads for mounting ssd disks, but of the 8, one was unusable.

    I'm not sure if this is a good idea, but it's not a good idea to turn the case upside down, but it's annoying when you start to mount the computer and realize that you're going to have to fiddle with it.

    Problematic

    A lot of ventilation in this case, which is unfortunately too light.

    The components of the PC are too heavy for the case, and this creates a mismatch between the side of the case that holds the motherboard, and the rest, which creates vibrations that make a LOT of noise.

    I have to put the pc down to avoid this noise.

    I clearly don't recommend it.

    perfect

    I love the transparent but dark front panel, which looks great with my LED fan! Perfect for a visible installation, but not too much! be careful not to put a CD/DVD player!
