I want to get a case for my new 15 MBP 2015. It was expensive enough I want to protect it as much as possible. I've been looking at the Tech21 Case but I'm starting to wonder if it will impact how the MBP dissipates heat. It does not cover any of the vents, but as the whole body of the MBP is practically a heat sync, could this cause problems? Does anyone have any insight on this?
