More or less looking for ideas from people who have done this.
I finally got around to building a recessed AV box behind the wall mounted TV.
For the next stage I could go the easy route and get a little faceplate that has a bull nose or brush but I am leaning towards having outlets for each cable type via keystone adapters. I'll need 12 keystone inserts and then another 8 for speakers (or a dedicated speaker-faceplate).
These guys http://www.darkstar.co.nz/wall-plates/inserts.html (found from another thread) seem to have most of the gear to do this, currently I can't think of a good reason not to do this :D
Any suggestions would be appreciated!
