Yes, I have a Pi4 2GB, it's still working as a second pi hole node. That's what got me into the world of self-hosting, but 2GB is not enough for a lot of things. I went from that to a N100 with 16GB of RAM, so the difference is huge and I think it's totally worth the money.

I haven't tried Immich, but I probably will once I have a better solution for storage.

I just have the included 500GB SSD and an external 2TB HDD, but I'm planning on getting a 4TB 2.5" SSD to put it inside the mini PC, since it has an extra slot for that.

I think you can get the full Orange Pi kit (Pi + sd + power adapter + case) for around 60 bucks on Amazon. There's also the option of going with a mini PC, you could find them from around 120 bucks.

I know you're not asking for hardware recommendations, but using an old PC may increase your electric bill way more than any of these options, so that's something to bear in mind.

Do you use both keys or is one of them the backup key?

I like to use the ones includes in oh-my-zsh. It's a big list, but the ones I use the most are:

gst --> git status

gcam --> git commit -am

gcp --> git cherry-pick

gsta --> git stash save

gstp --> git stash pop

gpsup --> git push --set-upstream origin $(git_current_branch)

grb --> git rebase

I'm an Android user and I never used Apollo, but wefwef is just amazing. It works surprisingly well, especially for a PWA. It will be my app of choice at least until Sync for Lemmy is out.

Just adding a comment so people will believe me when I tell them I was here when the "3 days without pooping" post happened :)

Good luck on your journey, OP!
