TommieG thx, but i still have a bumload of questions mroe to ask. I have decided to dismantle one of my fast desktop PC's, buy a VIA EPIA motherboard, purchase a very small PC case, and build a new PC that will fit inside my car somewhere (hopefully somewhere in the back seat floor). i am also going to purchase a liliput 7" XGA touchscreen lcd display for the car pc. as for the auto startup/shutdown module, i choose to go with OPUS, but i see theres an Opus 90 watt and an Opus 150 watt. whats the difference between them?
are there any other things i forgot? (ive decided also to put away the GPS/Navigation system for now because its money consuming, i want to get the basics down first)
