Thanks Leon,
No doudt MAC hardware is really good. I could run XP on it and attach a USB to serial converter as well (I use that myself to connect to switches, routers, etc).
PC and MAC's I don;t mind either of them....
I believe once I get the car my priority will be suspension and wheels... Let's see how the cash goes....
Carputer will depend on how easy I'll get my hands on a MAC mini and other parts...
Cheers,
Fabio
