Due to the fact that the fan is controlled by the I2C and not running all the time, this seems like a good fit for our application. We don’t need the extra draw on the system if the cabinet happens to be running on battery, and some of the Pi kits with the heatsinks seem like they wouldn’t be as effective as the fan for when extra cooling is needed. We have a Pi 3b on order, we need to get a 3b+ going for this to work it looks like. We should have some information to share shortly for this application, but it looks like a good fit overall for what we are trying to do unless the Ubuntu-Mate image for Raspberry Pi doesn’t run the stuff we are looking for.

"The Raspberry Pi Power over Ethernet HAT is a small accessory for the Raspberry Pi computer. It can only be used with the Raspberry Pi 3 Model B+ (launched March 2018). The PoE HAT allows you to power your Raspberry Pi using Power over Ethernet–enabled networks; for this product to be used, the network it is connected to needs to have power-sourcing equipment installed." If you really cared enough it appears that you could remove the fan if you felt it was necessary. "The PoE HAT is fitted with a small fan that is controlled by the Raspberry Pi via I2C. The fan will turn on and off automatically depending on the temperature of the main processor on the Raspberry Pi." Either way: this allows a Pi to be powered via POE fairly easily, right from the Pi Foundation. Previous methods I saw used a external adapter that was a step down/splitter like thing that was external to the board and not very clean. This thing is kind of cool and keeps the same footprint of the board.
