iNqUiSiTiVe - I took the "guts" (the boards, button contacts) out of the Logitech Marble and fashioned them to a piece of Modeling plywood (very thin plywood) and hardened the wood with resin. Keyboard is a ThinkOutside Stowaway Bluetooth
Ineffigy - Yes, its a hub. No, not powered... Just a "laptop" type USB hub I found at Walmart, because it fit in the space.
NotDave - The cord on the antenna is attached. 5dbi Whip. You could by a pigtail http://sharperconcepts.zoovy.com/cat...radiopigtails/, but the antenna's can be gotten cheap. Mine was 7.95. One thing important with Wifi is orientation. If you tuck a rubber-duck antenna in your headliner for example, I doubt it would do well. Anyway, my range extended by like 10 times with the 5dbi external. I can keep connection to my home wifi for as mush as two blocks.
agmsd & pepsibobby - Glovebox was the only option. I wanted it the armrest, but I couldn't make it all fit. Seats run too low. Trunk has amps and bass... and still needs to be a trunk. Glovebox worked well, because I didn't have to convert IDE to USB. It's not just parts in the glovebox, the glove box IS the PC with a Plexiglass window. When I need to take the PC out (for new additions or something) I just unscrew the glovebox and take the whole thing. Anyway, I like it....
