this is all true. i will be getting a true car pc power supply. probably a dsatx. Right now the pc is in my room and the car is far from finished. so Im going to finish up the xm, gps, ect. and just mount the power supply external from the dual din case. im gonna have to read more about these power suplies. my motherboard supports wake on lan. so the serial port is an option. or the conventional power button.
if anyone has any comments or suggestions post it here. this is my build.
