Else I may be able to extract some kind of dimension including mounting pillars and USB/3.5mm socket edge profiles from Eagle for you.  It would be extra kewl to go from board and component profile to inputs for your box modelling with some simple scripting!

It can curl round the box inside but maybe Mike can suggest the best layout given a general desire not to inject RF into the board, and/or maybe we can have a little hole to let us poke it out of the box if we want to, depending on how pretty it as to look.
The antenna wire should run perpendicular to the board for as much of 
its length as possible.  This could be either straight up above it, or 
in the same plane running away from it.  Avoid doubling it back.
