I've been thinking for a while about making a custom fiberglass piece to install my 15" computer LCD into the dash on the passenger side of my car and building a custom computer case to fit and be mounted inside the glovebox(I do alot of work with computers). I was then going to add a wireless keyboard and mouse along with a wires gamepad for playing games, watching movies, and listening to music in my car. Anyone done something like this.

 

There have been several guys who have installed car PC's before. It is alot of work and depending on what exactly you are trying to get from the PC, there is probly a much simpler and easier way of getting what you want.
