power switch ventilos minimum (7V), the only sound I hear, listening beside the case is that of my 'old' alim who nevertheless was a very silent PSU.
Hard drives do not agree.
Only complaint: the thumbscrews of the side plates are pretty hard to screw up / down and once unscrewed, the side-earth falls as heavy.
Switch-on button and USB ports on top before very practical.
Very nice finish and ability to hide all SATA cables by passing them through the back of the perforated plate supporting the CM.
