Review on UCTRONICS Mounting Raspberry Upgraded Rackmount by Sean Davis

I like that you can install 12 RPi 4 in this rack. I use a switch with 16 PoE ports (plus two Ge uplinks) to power them and a set of large fans to keep them cool. The only thing I would like to see is a mounting plate suitable for the RPi 3B+ model. I still have plenty of these and could use them in this rack for tasks that don't require the extra power of an RPi 4, such as: B. an Ansible controller or an MQTT broker.
