Isn't this all crazy more expensive then a routine device from say Mikrotik - here is $50 device that would give you gigabit line routing, advanced OS (if you want to mess with it), supportability, low power consumption ,built in network discovery (Dude) ,etc.

Why build homegrown monster that is 5-10x the price to serve the same function?
separate question of people with Plex complex, how many of you regularly and routinely watch content on the tablet/phone/etc? I have Plex (and lifetime pass), have it set up, and have near zero reason to use it that way.. what was the point of creating multi thousand dollar sound system with excellent HDR TV if you want to watch high def content on 5 inch screen? if for some reason TV is not available, well there is 100Hz nice 35 inch computer screen, excellent audio codecs, advanced headphones similarly available. Why in the world I would be torturing myself watching my BD disk rips on my iPad? I can buy the remote access/travel argument and even then I would just load up the device not to depend on wifi quality in the hotel..
because its fun to build your own.
Also its extremely rock stable, more so then a tomato flashed router.
With a lot of ram, and good hardware, its going to be extremely stable, and you wont have to worry about anything bogging it down.
You can hammer it torrents, have multipul people in the family run many many devices, do all sorts of stuff.
As for plex, its part of my jails on my freenas server.
I had way more then enough resources on the server, that plex was sort of freebie for it.
Since all my movies / media is on my FREENAS, it only made sense to add the plex jail.
Plex will work on most SmartTV's. You just need to download the APP.
Plex also works on PS3 and PS4, and Xbone. So you really dont need a smart TV.
The main reason why i love plex, is because i have slowly started to covert h264 into h265 to converse space.
H265 is very brutal on Andriod OS, hence why plex will transcode it, and allow it to be streamed on almost any device that can run the plex app.
