Hi, intrested in trying to put a comp in my car! Mainly for music purpose (at the moment i have an aux in, in the back of my head unit, but that involves looking down at my mp3 player down by the gear stick, which isnt too good when driving!), with maybe a motorized touch screen display. Has anyone got any tips of building one/experince? Have had a quick browse on the net and found some kits but thought they were a bit expensive so wondering about trying to build one myself. But not sure about a few things e.g.what would use for a PSU? Could i use the parts from my laptop?
