Here is my entry into the Club!
I am using an old box from work with a 4 port intel nic I got out of an old server.
I love how simple it is to create fully isolated lans. (my switch does not support vlans)
I have all my lans fully isolated except that the non wifi lans can talk to the printer lan. This was great as I was able to put my sister on her own lan because she uses xbox and other things that require upnp and I do not want that traffic on my lan. However, I did want her to be able to print to the network printer so I made it so our lans can talk to that one. Also I love how easy it is to lock down the printer lan and prevent internet access and only allow the ports the printer should be using.
Same for the wifi having it only talk to the internet and nothing else.
As you may have guessed I am enjoying exploring all the options in Pfsense to also get experience with it for use at work.
You can see the pic below for the system specs.
