Typically you would not use a single power unit like a Monster Power Center, but would opt for a single good surge supressor like a Surgex unit, then use a professional grade power strip (non-conditioned) plugged into the Surgex. The power strip will be the full height of the equipment rack it is going into so power cords don't have to be run all over the place, just a few inches over to the really long power strip.
You can pick up a long power strip from any dealer who carries Middle Atlantic equipment. Middle Atlantic racks are pretty much the industry standard for A/V racking.
