Review on 🔌 Micro Connectors Raspberry Pi 40-pin GPIO Expansion Board RAS-GP02 - Enhance Connectivity and Expand Capabilities by Mike Bogan

My original item had 8 acrylic tops instead of 4 tops and 4 bottoms and unfortunately I waited 3 months to open it so I couldn't exchange it through Revain. I contacted Micro Connectors customer service and they immediately sent me a brand new one which I received two days later which was perfect (and even had newer Raspberry Pi 4 heatsinks). layer, and the included fans are connected directly to the Pi + 5V and GND pins. The gaskets and screws are all of good quality and fit together perfectly. Acrylic has paper or plastic protectors to prevent it from being scratched during shipping. Unfortunately, since I use LoverPi PoE (Power over Ethernet) for my Pi, fans in the configurations they offer (hanging from the ceiling) are not suitable. Instead, I installed fans over the tops, which was possible since there are separate top and bottom sides separated by enough space to accommodate airflow fans. This would not be possible with most other 4 pi acrylic cases as they only use one piece for the top and bottom layers in the middle layers. I also had to use a pull configuration for the fans instead of a push configuration as the fans are so thin that they rub against the acrylic in the push configuration. You could probably get it to work in a power setting with some spacers on the fans. Even with this sub-optimal fan setting, my Pi 4s only hit about 70°C when cpuburn is running, so there's no throttling and no PoE issues. Hats get hot. The top Pi runs significantly cooler (10°C+ less) because the fan's airflow is unrestricted. You can see my final setup image connected to a TP-Link PoE switch. The case looks great and is very functional.
