content: Funny thing is, I have a Shield TV as one of my Plex clients :P I won't switch, because the hardware in my desktop is more powerful and it's easier to manage media from a desktop OS, but if I didn't already have a server this would be a compelling choice in lieu of a desktop.  It's small, it supports external storage, and with hardware acceleration it should be able to handle a few transcoded streams. I doubt my desktop's average Plex workload would be too much for it.  I usually only run one stream at a time, 480p for most things and 1080p for movies with strong visuals.  Depending on what client device you view from and what format your media is in, you might not even need to transcode.
