Okay, trim was done today. I selected a painter today as well, and hopefully we'll have paint up next week. I think I'm going to miss the superbowl, but if I can get the carpet in, we're going to stop for a while, and I will go ahead and set up the system for the olympics while I work on the entertainment center. Cabinets and bathroom stuff will continue in the background.
Here's the Sketchup mockup. I posted some off angle viewing as well to show some of the dimensions. There will be pieces of trim here and there covering joints and seams, not worth the effort of putting into the model.
The first is what it will look like with the screen up. I can't decide if I want to paint the inner area black to better conceal the TV and speaker bar above it (for everyday, simple viewing) or line it with 1/4 plywood to match the wood. I think I'm going with African Mahogany, it's as cheap as maple right now. The AV rack will be installed behind the door all the way to the right. It will be a pocket door and will be open during viewing. The sat box will go in the cubby up top. It runs continuously and will need ventilation. There was no good place for an AV closet.

Next is the screen down. Da-lite has 3d models of their screens. I used the 106 and stretched it out to 110 diagonal, it's not perfect but easier than building my own screen. The casing will be recessed behind a hood with crown. The sides will also be partially concealed by the trim flanking the speakers. I'm hoping this will create a bit of a shadow box around the screen.

Looking up into the hood.

Looking down

Next, I need to make cut lists for the plywood and solid wood so I can minimize waste, and then build up the courage to buy all that wood. This will be the largest woodworking project I've tackled.
Thanks for reading.
