Hello, I recently bought a Cooler Master N200 Closed and a Cooler Master MasterWatt Lite 400W. There is no indication how the power supply must be mounted. I immediately assumed that the ventilator of the power supply must be at the bottom, directly over the filter in the bottom of the case. However, on all little drawings in the instructions I see the power connector above the switch (0-1). Is there any instruction available. Air flow is very important. Thanks in advance.
