This box may contain a micro-ATX card associated with an ATX power supply. It has a good fan at the back of the case. During operation, we hear a slight hiss that does not prove annoying at all. The dust filters are numerous and all have a good finish.
Small problem: the explanations to remove the front are very succinct. Outside, it is necessary to remove or to place the hard drives. These are placed vertically, but unlike my fears, this does not pose problems.
