That white box on the wall at the rear is a space heater. Dimplex 2000w convector w/ thermostat. Pumps the heat out pretty good, but will likely hardly switch on.

The gear is going to live in the AV pantry cupboard outside the room. I am using an IR repeater sensor behind the screen wall. It just dawned on me last night after vaccuming I hadn't ordered any of the sub and HDMI cables yet. Doh! Just as I zeroed my visa balance....
