I've spent about two hours reading up on all the carputer threads, and rather than open a six-month old thread I'll post here. I'm getting ready to build mine and I'm wondering for anyone who already has one in the glove compartment, under the seat, or anywhere in the passenger cabin, do you notice the noise of the cooling fan, or heat from the box at all? I'd like to put it in the trunk so it'll be quiet, but it would be a lot simpler and take a lot less wire to put it under the seat.
