Good Evening All, I'm looking to build or buy a NAS to also use as a PLEX Server. Every time I build a new computer I end up transferring files around and nothing is in a centralized location. I have about 4TB of MP3's and Pictures and backed up movies. I access the internet and my current files via several media devices ((2) Xbox One, PS3, Xbox360, Nvidia Shield). I live in a 2 story house with wireless Asus RT-AC87R Routers on each story. I'm on Comcast high speed internet I don't plan on creating a huge catalog of movies/videos, just backup a few Marvel Movies. My current problem is that I'm not always able to access my files due to UMS or sharing issues. And none of my files are consolidated in one place. I just bought 2 more X300 4TB HDD's (+1 in main PC) My thought is to use spare PC#1 and build this Server/NAS with FreeNAS or similar. I have decent Windows skills but no linux, I'm sure a GUI would be easy to learn though. I would need some kind of redundancy, I don't want to lose mP3's and pictures.

I really don't want to spend much money as I have a lot of parts, maybe hard drives though. And FYI I ahave about 22 GPU's mining that I could put in any of these machines. (RX570,RX580, 1060, 1070) I can't see ever running more than 3 streams. Please help! I'm sure I missed something.
