Solved: CAR PC? will it work? HELP

Hi there

Newbie to this but I want to put my pc in my car. Was wondering if I take pc tower with 500w inverter will pc run if I hook everything up. Was looking for wattage regulator but could not find place that sells it (cape town, south africa ).

PC parts- 60 gig ssd, am3 mb with dedicated graphics, athlon cpu, 4 gb ddr3 ram, 500w psu, 7 inch touch screen, running window 7 ulti.

Reason for car pc is as monitoring car specs (wheel pressure, parking sensing, alarm...) and as media player, gps etc. Basically to add electronics to my car that it did not come with, Electronically modify it or pimp it out. Not so much into speed or heavy sound.

Car is Chevrolet aveo 1.6 hatch 2010 (black).
Was thinking car battery-inverter-pc. I am not electrician so car or pc maybe both would blow up.

I know a in-dash player from Kenwood or other manufactures would be easier but wouldn't a pc have more functionality and connectability.

Plz help me, what do I need to do? Will it work? or am I noob for asking? lol
