I have the overhead compartment for my old TV and I replaced it with a 32" LED in the dining area...

So far, I have only covered the opening with a mirrored door but I'm working on plans to turn the space into a wine cabinet. I'll be converting a 12V powered cooler for the cooling part and I'll double insulate the box and add wire racks to hold the bottles...

Re-wiring for your new location is not too tough if you can get plent of wire-mold or if you stay close to your cabinets (you can use the inside back of the cabunet space to run wires too.)
