I'm having trouble finding a proper starting point for self hosting, so I am curious on any resources you'd recommend, or even some build lists / pre-built devices.

What I want to do:

Important

1. Host some applications like TinyTinyRSS, Jellyfin, GitLab, and Nextcloud which I'd want to be accessible in my home network
2. Use the computer as a NAS to back data up and have it easily accessible on my desktop and laptop
3. Have a piHole

Optional

4. Access my hosted applications from outside of my network
5. Use tools like Radarr to automatically download things from torrent lists
6. Use it as a seedbox

The reason the last three are optional is because for that I'd have to expose the computer to the outside network, which has a whole bunch of benefits, but also a whole bunch of risks I am likely neither capable of nor comfortable with working around, so unless there's an easy fix (number 3 might be able to be handled via a VPN?) they're a problem for future me. For anything further I think I can just go from here once those requirements develop

I have already skimmed through some articles, watched some build guides for both NAS and home servers and honestly I just don't know what I need, both in information, hardware, and software.

• Should I separate the NAS and Home Server, get a separate device for the piHole, or just have all three in one?
• What hardware would be suitable for this?
• Should I buy something off the shelf like a mini PC (for instance an Intel NUC) or one of these fancy prebuilt NAS devices where you just need to plug in some drives or build my own?
• Would it be smarter to go with a Linux distro as the OS, for instance Debian, or should I use something like Unraid or TrueNAS which from what I can gather make setup more convenient and even handle docker images for you?

I am somewhat comfortable with Linux and the command line and have a budget of about 1000€, but if I can get away with less that would be great, and I can also stretch higher if needed for my requirements. I am also very new to self hosting and my networking knowledge is not non-existent, but limited.

I'm just a bit lost and would love some beginner-oriented resources or direct advice, thank you!
