Edit: I've just purchased an Unraid license. I'll give it a go and it may not turn out well, but for the time being, the question is settled. I appreciate everyone for providing insightful and informative answers!

Hey everyone,

I've recently bought myself a NUC (NUC11TNHi3) that I intend to run as a home server, using many of my external USB drives as the storage.

My use case is very narrow. I'll use it as a Plex server and seed/leech torrents with it.

I've never built a home server like this before (I did dabble with it on a RPi, but that was just for PiHole), so I've never had to research what operating systems are available to me. After some research, I narrowed it down to two options.

1. Windows
   This option is the most straightforward given that it's the system I'm familiar with the most. My use case is also very narrow, so I could set everything up in a couple of hours. All I'd have to do is install Plex server, a torrent client, exposing them to the outside world with port forwarding or Tailscale (never used it before but seems easy enough), and share my external USB drives locally so that I can access them using my regular desktop computer at home. The downside of this is that Windows can be finicky. I'd also prefer to have my drives pooled under a single drive. A cursory research suggests that Windows can do this as well, but not in a way that inspires confidence.

2. Unraid
   I hadn't heard about this since last week, but it seems like a nice option. It costs money, it's proprietary, and I'd likely have to reformat all my NTFS drives to be able to use it but I was wondering if this would be the best long term solution. The learning curve will be there. Arrays, cache drives, share drives etc. are terms I'm not familiar with (though I can guess what purpose they serve) so it will be more time consuming to set things up properly. But given how narrow my use case is, as elegant a solution as it seems, is it necessary? I'm only considering this because seems like this is the best purpose built OS in the market right now.

Some clarifications:

• I'm sure someone will suggest a Linux distro. I have used Fedora as my main OS for a couple of years and I was quite happy with it, however I could never wrap my head around the Linux permissions structure, which Plex is awful with, as it creates its own user and look for drives under that user. I must have spent hours and hours to make Plex read my external drives properly before, but I've never managed to make it do so without some sort of hacky way and I don't want to do that with my home server. I don't want to have any doubts that things can go wrong. I want something that just works. (If only Synology had a capable device that could handle multiple simultaneous 4K transcodings. I'd have just throw my money at them instead of buying a NUC.)

• My use case will remain narrow. Maybe way down the road I can automate stuff with Sonarr or Radarr or stuff like that, but I don't think I'll ever consume enough recently released stuff to justify it. One thing is for certain, I'm never going to host my password server, feed reader, or something like that on this device.

That's about it. What should I do?

Given that I'm a novice is this area, I'd be all ears to listen any other related or unrelated advice for someone who's just starting to build their first home server.

Thank you in advance.
