aren't we doing this already? When you try to overclock your CPU or GPU it says "if you do this you void your warranty", and that's pretty much it. It's not that simple but it's also not that hard, there's often a pretty big line between trivial modifications or modifications that might fry whatever device you're dealing with.

If there's a gray line it'll come down to some third party judging it but I don't think this is any different from say, verifying an insurance claim.
