Figured I would chime in, since you are flaunting my hardware in that video thumbnail.
I have two of these boxes, one is running my current pfSense and the other is kinda an Ubuntu Server Sandbox (I am currently running Home Assistant on this dedicated device).
One thing to note with pfSense and NIC compatibility. I had issues using the VT1000 4 port NIC where pfSense would lock up after about 2 minutes of power on time. @manbearpig2012 and I have both tested using a Intel I340-T2 ($15) with this hardware and it works perfectly fine.
