Looking for concept validation for a PC

[BrandonPonYoutube]

Good morning LTT community,

 

I have a concept that I'm looking for validation or comments on regarding my in-home pc experience.

 

What I want to do is use a central PC as a plex media server and a Steam In-Home Streaming machine to serve content to TVs around my house.  I want to be able to leverage a powerful PC to do the heavy lifting for plex transcoding and to be able to serve as a network "cloud computing" machine to run my steam games off of and stream them to the same TVs.  Basically what I want is to have one nice machine stream my own content to the TVs in the house to watch movies or stream games

What I have so far:  I have a Dell XPS 8500 with a 16 GB of ddr3 1600 and a R9 280x.  storage has been across a 120 boot SSD, a 2 TB storage drive and a 1 TB WD Green in a enclosure attached via USB 3 to the PC.  at this point the PC is connected to my living room TV.  I've set up a plex media server pulling from the external hard drives content for its library.  I feel like Im half way to my concept because i can use plex and chromecast on my other TV to stream my content to that other TV on the network.  but I am wondering about the Steam Streaming.  whats best?  I have thought about building a HTPC in a micro ITX box for each of the TVs and sticking the main tower in a closet. I've looked at Intel NUCs as a barebones alternative as well.  even considered buying cheap pre-built PCs to connect to each TV for the steam streaming but I don't know what to expect and what path is best.  I'm not so concerned with pricing of the setup as long as the end result is awesome.  on the client PCs id probably use Kodi to serve the plex content unless there is something better.

 

What do you think?  where do i go from here?  I have a few ideas but i dont know what would serve my desires the best.

 

Thanks for reading.
