since over one year I'm using the WRAP-Board. My WRAP has USB and WLAN.
And was very unhappy with the standard enclosure.
So I decided to make one. A better one. With milled front and back. With
labels ... not cheap - about 90 eur.

Wiki (german only at the moment):
Maybe you find the files suitable for your own enclosure.
