RPi PoE Hat
-
Just thought I'd let people know...
I have one of the official PoE hats for RPi and it works great.
If you do an rpi-config update from the menus, the firmware gets installed which drives the on-board fan (not necessary for the PoE functionality, but an extra bonus as it runs via I2C and therefore doesn't interfere with your GPIOs).
The fan is pretty tiny and quiet but good - I was getting a consistent 60C with just the fan (no heatsink etc.) in a fairly-enclosed case when maxing out the CPU with the "stress" tools, and it never needed to throttle the CPU. In-game performance shows the same kind of temperature control with zero throttling when maxed out.
You can now power your RPi entirely down the Ethernet cable (up to 2.5A) and it works really well. You would need elongated GPIO header pins if you want to use other stuff on those pins, but it doesn't block them.

And a PoE enabled router/switch port.
