I have been intending to do this very same thing with a touchscreen. I'm having problems locating the right cabinet locally, though.
One of the reasons I've passed on a few cabinets is because the face of the radio, the tuner and dials, were mounted like the first picture, which I feel would make it hard to view the screen, whereas I'm looking for cabinets like the second picture, where the user doesn't have to stoop to see the screen.
I'd be very interested to hear your thoughts on how user friendly the vertically mounted screen will be.
