The cables should be OK, if you use quality ones (well shielded), thta don't exeed 5m in lengh.

As I really want to do this in my next car, i just wanted to know, is it OK to have the PC in the boot? Won't the video signal degrade running the length of the car? Also will it affect the keyboard, serial, USB cables etc? Although we are talking Ford Fiesta here, not the mobile mansions you Yanks drive so maybe it wouldn't be too bad.
