This is a followup to my awesome Old Skool NES Classic RetroPie build. When I posted my build on Reddit several users that already had the case noted that the case tends to get very hot.
That’s not good, but since the case is so awesome I was determined to find a solution. This mod requires no soldering, no drilling, and is dead simple and cheap. It also does not modify the look of your NES Classic RetroPie setup at all!
