I work at home and so on PC and in this case, it was always the fear of a technical problem that would make you lose more than one workday. This kind of machine allows me now to sleep on my ears. The installation and connection of the various elements require some effort and a little concentration, but nothing insurmountable. My apprehension was to add the sound of extra ventilation than my PC. This kind of consideration can smile but as it is a workstation on which board 8 to 10 hours a day, it's important. I am now reassured on this point, the tower matrix is silent.
