Have Plex with HDHomeRun OTA? How do you like it?

I'm looking to pair my antenna + HDHomeRun Connect with a Mi Box running Plex, using an old computer as my Plex Server. My goal is to make a setup that is easy enough for my SO to use without much of a learning curve. Anyone else running this exact setup? How is your non-techy SO holding up using the Plex GUI to find, record, and watch shows?
