So I love my gnexus but I hate that it's plastic. It makes it feel cheap to me. I'm going to have this phone a pretty long time. Is there any company that will actually replace the plastic chassis with a metal one? I'm probably going to have this phone well past my upgrade (which is a year and a half away anyways) so I'd be willing to pay a decent amount to have that done.

If not, what are the best metal cases? Something pretty minimal, I don't want a tank but I still want the phone to feel solid. I tried a Google for both of these but I'm at school and kind of swamped with midterms atm. I use an extended battery so the case would have to fit that. Thanks
