Pi is perfectly capable of running Plex. Maybe run it on there with some cached data on the Pi and then the main content stored on the server. Then when accessing Plex, it will have all of the content showing what is available but in the background will be starting up the main server with the main content. I guess you could just attach an external HDD to the Pi. Thats worked for me before.
