Need advice on new build

[need4swede]

Hi Jellyfin forum,

I've been using Jellyfin 10.8.10 since its release. I am currently at the stage where I am planning on building a new server, but could use some guidance.
My current setup was Frankenstein'ed together using whatever was available to me at the time, so it's not an ideal setup. 
I want to start fresh - but could use some help.

Here is my current setup:

• Dell Optiplex 7050 (i7-7700) with Nvidia T600 for HWA transcoding (Runs Jellyfin + Caddy [duckdns])
  
• Mac Mini (i7) connected to a OWC Thunderbay 8 (128TB Raid 10 via SoftRaid [64TB usable], connected over Thunderbolt)
  

The Mac is my file server, and I use it to store my Jellyfin media. The Jellyfin server accesses the file server over my local network. I don't have any performance issues - streams are pretty instantaneous. Streaming over internet is a hit or a miss, depending on file size.

I want to build a new server that runs the Jellyfin instance and hosts the media at the same time.
I've been wanting to pickup a new 12/13th gen Intel CPU with a UHD 770 iGPU and pickup a A380 sometime in the future if AV1 gets supported.
But where I am stuck is figuring out what OS I should go with. I am very comfortable with Windows and macOS, but Linux is a new territory for me.

I have a lot of folks recommending TrueNAS, saying I can use it to host my files using ZFS, run Jellyfin and reverse proxy over the internet.
But a bit intimidated by the approach, and if it's even worth the trouble. I was going to put a Windows build together with a 13700k and a board with onboard Thunderbolt - but people tell me that Windows Storage Spaces is terrible for Raid.

What's the best approach here? Is there a Linux option that I can use that would serve me better? Or would I be better off going with the Windows route?

Thank you!

without judgement (as i am not concerned with what you prefer)

i think it would be best for you to stay with an OS you are comfortable with using
i prefer linux so i use linux but if i were more comfortable on windows i believe jellyfin would work just as well there
but i have never used macos so for me to jump into macos and try to setup a server it would be a disaster

i do not recommend using TrueNAS or other such operating systems, if going that route it would be easier to setup a bare bones ubuntu or debian jellyfin server as they are officially supported and even have setup scripts https://jellyfin.org/docs/general/installation/linux

I like the previous advice, stick with what you know for know.
It is great fun to learn other technologies and build things.
If you want to try linux, be aware there will be big learning curve,
so make learning linux first a side project.
Whatever you migrate to, make sure you've taken time to learn/study before making the leap.
