If you are putting blanks and vent panels in the rack to make the world more tidy you might consider fan cooling the rack, it can get a little toasty in there, even a couple of mains fans in series to keep then quiet helps to pull the hot air from the top of the rack, remember to vent the bottom for cool air in though. I use a cheap fan panel bought from CPC, DC fed from a wall wart, little bit noisy if doing an orchestral job so I either move it away or turn off the fans.
2U APC 1400VA UPS in the bottom, iDR10, Gigabit switch and a connection panel job done. Read somewhere that Network switches used for audio don’t like getting too warm, not sure where. Never had trouble with the set up, well only lifting it[8D]
