Lg G4 Aluminum Metal back cover?

[AC Question]

Hi, I'm thinking of buying the LG G4 coming from the HTC M7 but that plastic cover is the only thing holding me back. Has anyone found a metallic silver or black back case I can replace the plastic with from a third party seller? I did a quick search but I can't seem to find one.

(The leather is totally out of the question)

Thank you for any help.
