AdGuard Home and blocky are other popular options. I switched over to AdGuard Home a while back because it supported DNS over HTTPS although I’m not sure if that’s still a relevant reason. I run AGH as a docker container but it is easy to run in a LXC or VM. There’s also a tool to sync configs if you need multiple instances. Notice: AGH block lists are formatted like uBlock Origin lists so you will not be able to use PiHole style lists.

DNS based ad blockers won’t work when ads are served from the same place as the content. Which is why DNS based ad blockers don’t work against Twitch or YouTube. So YMMV.

If you’re looking to block interface ads and select streaming service ads there are block lists available like this one. The game with smart TVs is blocking the ads breaks the TV a little because sometimes it calls back to the same servers for updates and misc info like weather.

I run a Plex container on Proxmox and have it connect to my Armbian/OMV NAS via SMB. The way I got SMB shares working was to mount them from the Proxmox host and then mount them read-only from the container. (better security ig) I’d be happy to share my configs although it might take me a couple days to pull them up.

Another alternative I’ve been thinking about is buying an external drive rack and attaching it to the outside of my server’s PC case. Then running SATA extenders but this might not be possible depending on the kind of mini PC and I’ve heard extending power can get dicey if you have more than a few drives.
