Advice on setting up new home with media server
I'm hoping to get some advice; moving from an apartment to my first house and I'm trying to plan/budget the best way to set up my media server.
My current situation is I have a mid-range Windows PC on my network running Plex server with 2 2TB USB 3.0 drives connected, with various movie files (1080p x264 mkv's 6-12GB, and 4k x265's about 20-40GB) I currently have 2 TVs - a Samsung 4K and an old Sony 1080p - but will be adding another 4K TV soon after moving. I haven't had many issues playing the 1080p content, but when I want to play 4K mkv files now, I need to attach the drive directly to the TV otherwise constant buffer issues.
What I would LIKE to do is just keep all my files on a NAS and stream through my network to the TVs. I'm just not sure what the best option is to ensure no buffering issues. Its doubtful both 4K TVs will be playing simultaneously, if that matters, but the 4k and 1080p likely will. I've looked at the Synology DS416play (and read some reddit posts about upgrading RAM to 8GB), heard some good things about Shield TV, where I could use that locally (connected to the TV) to stream files off the NAS (and could potentially go with a 'cheaper' NAS, and I've seen some QNAP devices that actually have an HDMI port on it. Havent looked too deep at the specs to know if its HDMI 2.0
Bottom line, are any of these options potentially viable for what I'm looking to do? If not, please steer me in the right direction before I lay out money and find out later I messed up. I'm looking at a budget of around $800, not including hard drives, if going the NAS route
