Sonarr + Picard

Do you mean Lidarr? Sonarr is the TV one (confusingly).

CPU-heavy process

Sounds to me like a hardware issue: you’re overheating. Find a way to monitor your temps. I’m not sure how to do this on Linux, so I’m open to suggestions too.

Given pihole’s recent record with updates, I’m not sure I want them firing automatically.

Unfortunately I can’t remember whether I downloaded pihole from some package manager within DietPi, or whether I used the instructions on pihole’s site. It’s not hard either way, it’s really just one package.

I run it for my pi-hole. It’s been great. It tells you when there are package updates when you log in, which I find helpful.

How are you geoblocking?

I know Kodi running the Jellyfin plugin on LibreELEC works great on a Pi. I’m not entirely sure if/how Kodi supports YouTube, but there are so many plugins available it seems like it must.

Not the person you were responding to, but I’m quite happy with my DS220+. It’s on 106 days of uptime after a power out. The interface / OS is very friendly. The only downside is the weak processor which makes it inadequate for things like Immich’s AI or heavy Jellyfin use - but you get what you pay for.
Re. lemons; are you sure it was the NAS that had issues or could it have been the drives? Mine is loaded with WD Red drives iirc.

Obsidian synced via git.

I would prefer to have GPUs for under $600 if possible

Unfortunately not possible for a new nvidia card (you want CUDA) with 16GB VRAM. You can get them for ~$750 if you’re patient. This deal was available for awhile earlier today:

Or you could try to find a 16GB 4070Ti Super like I got. It runs Deepseek 14B and stuff like Stable Diffusion no problem.

Can’t figure out why you would use Plex over jellyfin

Probably the biggest reason is that it makes it so easy to securely share across the internet. With JF you’re on your own and you can really fuck things up. If you’re just running it on your LAN the JF is the obvious choice.

Everything I hear about Nextcloud scares me away from messing with it.

I’m just running into this now. It also won’t let me log into the web interface. I’m glad I experimented with a second install before upgrading my primary pihole.

I tried Kopia but it was unstable and janky, so now it’s whenever I remember to manually run a bunch of rsync. I backup my desktop to cold storage on the first of the month, so I should get in the habit of backing up my server to the NAS then also.

Raspberry Pi 2 or 3 (can’t remember which) controlled through the TV with the remote. It’s running LibreElec (Kodi) with the Jellyfin plugin. Discoverability isn’t great through Kodi, but I can always use a computer or phone to find the media and cast if I need to.

I believe the issue is only with Tailscale Funnels. With Funnels, the data runs through TS’s infrastructure so it’s subject to whatever kind of bandwidth limitation they feel like enacting.

As others have said, you don’t need to know how to code, but you do need to be comfortable editing structured documents, so knowing a little programming does help.
Unfortunately, Nextcloud and email are two of the most difficult things to self-host. This is by reputation, I haven’t tried myself. Email is supposed to be particularly difficult and the usual advice is to not bother.
Jellyfin is pretty straight-forward as long as you don’t have a weird hardware decoding setup and as long as you don’t want remote access. If you do want remote access you need to use third party tools to do it securely. If it’s just for your own use then Tailscale makes it really easy. If you want to share with non-technical users it gets messy.

I went with Debian and I use Docker for containers. I considered Proxmox, but I didn’t end up trying it. PiHole is a good application for the Pi Zero (I have an early generation Pi dedicated to running PiHole), but you could also run it on the Beelink.

I strongly recommend you download Obsidian and keep hyperlinked notes on everything you do and links to every tutorial/resource you end up using.
Have a place to keep all the passwords your services will end up needing. A password manager is the best option. Make the password on your admin account on Debian (or whatever) easy to remember and enter, since you’ll need to sudo a lot.
If the Beelink comes with a copy of Windows installed, you can recover the key from within Linux with the following command:
sudo strings /sys/firmware/acpi/tables/MSDM
Then you have a spare Windows key should you ever need one.
