Review on 🖥️ Geekworm Raspberry Pi 4 Case: Ultra-Thin Aluminum Alloy Passive Cooling & Heatsink Case for Raspberry Pi 4B – Compatible with Pi 4 Model B (N300) by Holly Robinson

I needed a Raspberry Pi case that would give me access to the GPIO pins so I bought this case. The case keeps the Pi cool and only heats up slightly when the Pi is running. There are no fans, but most CNC cases with fans aren't of much use if you install a hat, since the hat will block airflow from the fan. I had no problems with WiFi with the Pi case installed. There are a few other CNC cases cheaper than this one including one from Geekworm but I like this one because it completely isolates the board making it look more professional while also allowing access to the GPIO pins like monitor - and camera connections.
