micro towers are the way to go, installing a monitor where our radio and cd players are, the three options for the place to put a computer would be either in the back in the trunk, the console area, which to my knowledge hasnt been done yet, or in the glove compartment, the glove compartment may seem small however theres a clip that you can sort of press in that makes the compartment open up even further
the problem with the trunk is is that i have subs in the back of my car, those magnets would screw up the computer big time so thats out
if you must know what it would be for, it would be for media playback, audio and video. i have found a few articles online on ECU readout but that would be a little involved. there are many things u can do with a carputer, its just that its a pain to install them lol
