Review on Retroflag NESPi Case+ Plus: Power Button With Safe Shutdown, Cooling Fan & Heatsinks For RetroPie Raspberry Pi 3/2 Model B & 3B+ by Daniel King

Great little case. Follow the instructions for how to install a simple program. This will make the power and reset buttons work correctly. It is so nice to be able to press the power button, a script runs automatically, and then it shuts down properly. I am using with Pi 3B. It is running retropie. It will shut down the system, even if mid game emulation. I also find that now I no longer get the overheating icon in the upper right while running some more intensive emulators. Probably because of the fan. Be sure to install the fan facing the correct direction. It only blows one direction.I also like the cool NES look. The buttons feel just like a mini NES. Super fun.
