    Top

    Everything is there: screws, shock absorbers, etc. Clean, neat, well finished, and apparently sturdy. This small, compact case is very good. It easily holds an 850W PSU, an ATX card, and an RTX 5070. Keep using Chronopost! They are by far the best, with impeccable service. Very happy.

    an excellent box overall, despite a few shortcomings

    After trying a few different bodies over a few weeks, I stuck with this one.
    2 fans 14cm:
    + good quality fans on the front.
    + fastening from the inside, which makes it very easy to install filters from the front
    - the support doesn't allow you to adjust their height.
    1 fan 12cm:
    + at the rear (not supplied)
    + this fan is height-adjustable
    + numerous cable channels around the motherboard
    - in the corners of the case, there are few or no cable channels (frustrating for cable routing)

    + filter under the case easy to remove.
    - The shape of the filter means that the underside of the case is not flat.
    - 1 single USB-C connector
    - it's not possible to move the connectors to the front.
    I made a few modifications to the case: in the end, very good air-cooled performance (cpu at 55° and gpu at 50° in 1080P at 144 fps) with very little noise.

    Very good box

    This case is of very good quality, looks great and the efficient cooling capacities mean that the fans can run at low revs and maintain a very good performance/silence ratio.
