i'm using the ion n230's which work great, not sure about others.
What are you going to do for lighting, thermostat, alarm, etc...
make sure you wire everything, overwire, whatever wire, cat6 wire, quadruple wire, KNX wire, whatever, make sure you got it in there before closing the walls.
Well going overboard there, but you got my drift, you can pretty much send anything over cat6 now, so make sure you have extra lines.
if the closet is big enough, why not put everything in there and use some hdmi-cat6 converters to drive you tv's and/or ir/rs232
i know that's my ultimate goal.
