Notes:
1. The units dimensions are scaled to the size of the controller expansion
diagram. The values represent the size used to setup the units in the controller
expansion, it is not the size of the units themselves.
2. The attachment holes along each side of the controller expansion are divided
into units of measure called EIA units. Each EIA unit (U) equals 44.5
millimeters (1.75 inches).
3. The controller expansion is 37 U high but only 35 are usable, one U must be
reserved at the top and at the bottom for proper cooling.
