Without knowing what will be in the rack, it's impossible to know. If it will always have open sides, I wouldn't worry about cooling. If that ceiling vent will usually provide for removing warm air, it won't be a problem- convection will do the job, but not if the side and back panes are in place. If you do enclose it, open the top, use fans and make sure the bottom of the rack has vent panels and the fan can move enough air. Still, it's hard to say without knowing if it will have network gear or a be full of inefficient audio amplifiers.
It'll be mostly an RTI based automation/distributed AV setup. I was mindful when choosing gear -- using class d amps where possible etc.
The only exception will be the gear for the dedicated theater -- I'll be using some beefy amps for there -- but then again, they won't be in use all of the time.
