One thing to do is set it up so you can add anything like Docker Containers that you might want to control.
I am looking into creating a Docker that will hold SABNZBD and scan a few indexers for RSS for a short term holding. I used an 256G SDmicro chip. I then set the mount points. the emmc that is installed points to /opt for docker use. I format the remainder of the 256G chip for three folders. /Watched /Downloading /Failed
Remember to point to each as a mount point for SAB. Setting your system to only run 1 hour a night is more than enough to grap any file that is in your cart on the indexers you visit. To learn more. Study up on RSS and SAB. A old website I follow is https://www.cuttingcords.com/
It is not very up to date but will give advise on how to run a plex server on windows. You just set your network shares to see the folders on the H68K and go from there. Hope this helps
