As a Plex guy myself, I’m sure you could, you will need to transmit over WiFi or get a USB nic. Inversely is you are looking to make a Plex server I would suggest looking at used HP elite desk mini’s, they have much beefier CPU’s, 6th and 7th gen i5 processors and gigabit nics. You also have the added benefit of m.2 slot and typical data 2.5" caddy
