It's actually Window's XP with the Media Edition version that I can go into while driving. It's too hard to find a small mouse arrow on a 7inch screen otherwise but the jukebox format is great for scrolling through all my media, video, pics, and music on the move.
Couldn't tell you much more about the PC, my mate Daniel Bradshaw designed it and built it for me. It comes in a Molex case and has DVD burner, plenty of USB's at front and rear, about 40 gig and is pretty quick. it comes with 12 volt and 24volt power leads, so the 12 volt one is hooked into my car but when i pull it out I take it inside and connect to the other lead in my study. I have a HDTV connection and Broadband Internet also and it all handles without a problem so I'm very happy with it all!
The only pics i've got at work with me are attached. they're a little messy but it shows you the build behind the scenes.
pic 1 is the hidden PC, you don't see it once the screens are in but can still easily reach it to use it. The grey box on the right of the pic is the sony AV input thing (hidden neatly of course), so you can plug in a PS2 or VHS player or anything with red/white/yellow cables.
pic 2 is before i started wiring everything up. i had to upgrade my battery to an optima which was so much bigger so i modified the shelf by angle grinding it and welding it wider. The rest of the stuff there are for the fuses for power converters, amplifyers and other electronics.
pic 3 shows you the back seat install before i wired it all up. used dynomat Everywhere! all the doors, boot, back seats etc completely finished a bulk pack of the stuff!
pic 4 is the spine as we were designing it. I sent off all the shapes to my mate Darren who then provided me with all the parts and the buffing machine -took forever
