For a couple of years, I have been serving Plex to a few friends and family from an NVIDIA Shield Pro on a gigabit fiber. Before that, I served from a Raspberry Pi.

I have basic Linux skills, and my dream is to build a more automated setup. Unraid OS with Plex and -arr apps looks great to a non-expert like me.

So, I just picked up an unmolested original Lenovo ThinkCentre M710Q 7500T with 16GB RAM, and a 256GB M.2. I have a spare 2.5" 2TB Samsung EVO 970 SSD that I could put in it; I also have a 3.5" WD Red 4TB external HDD.

Here are my questions:

• Do I need more RAM to be able to serve four 1080 streams at once?
• Should I use the SSD or HDD, or both?
• Any other advice or suggestions? It’s appreciated!
