That trim could be used with the proper sized chassis, the hard part would be the LCD mount since there is no trim on the top or bottom. It can be done, would require some more thought than the ford metra kit however.
I am considering the nano as well as the pico board, as this would free up a lot of room. The problem with the smaller technology is it may prove too cost prohibitive. I am looking to manufacture solid yet affordable units. I used the Intel little valley board and must say I am impressed with its speed and price. Using a laptop drive and the M3-ATX would allow all components to reside inside the chassis.
