Front Panels
Basically, this is another chance to play around with configurations and design tables.
Front panels are used in server racks (and a multitude of other distribution racks). The height is designate in Rack Units, which are multiples of 44.45mm.
The point is to use a single design, but vary some aspects as the front panel increases in size.
An enclosure is included to provide some understanding of how a front panel might be used in real life.
