A medium-sized box which is actually very large, well appointed, lots of space, quick release systems for devices (scanners, hard drives 3.5 ', 2.5' SSD), the front door that gives access Direct to 2 hard drives, multiple passages for cables ... associated with 3 fans that seem efficient and silent ... I find this really very good (compared to the boxes I could know so far .. ..) balance at 75 why hesitate !!!!
