Scott_fx was actually one of the reasons I decided to sign up for this forum.

He did an awesome write-up on C5 Corvette audio over on the CorvetteForum, and linked to this place.
As I mentioned in my
first thread here, I'll be putting the carPC in an '01 Corvette convertible. The case design will be a big part of it. I plan on building up the pc to 'normal' pc standards for the time being, and stowing it away in the back of the car as a mobile media center for when I'm parked and hanging out with friends. I'm likely to wait a year or two before I go about dropping a good chunk of change on speakers, an amp, and one of those fancy transflective screens (never mind the fact I'll have to hack up and redesign the center dash piece on the 'vette). Due to those facts, the case will have to be modular / upgradeable to a degree to allow for the changes that will happen when it's turned into a true carPC.
(edit) Looked at Veritas' stuff, definitely badass. I'm more likely to be going with an acrylic case, both because of the upgrade possibilities, and because I can heat-bend it into some
neat shapes and use some rather cool colors.
