We are thinking of building kitchen cabinets to support a microwave (Miele Speedoven) with a cubby above the microwave able to hang a 24" LED monitor recessed a couple of inches back to deal with rising steam.

Imagine a double wall oven cabinetry but with the above oven being a TV.

Questions:

1) Should we worry about rising steam even if the TV hangs back a couple of inches recessed?

2) Should we put a door in front of the TV to close off if we use the microwave - would be cumbersome.
