Your server needs to have a static IP address. Once you have that, and have your DNS service set up, then you should be able to update your domain(s) to point to the new DNS. This new server doesn’t have to be your primary DNS entry for the domain(s), but it should be one of the first two entries. And that’s pretty much all you need to get started.

One other consideration is setting up the master/slave status of your DNS servers so you only have to make updates in one spot (helpful to ensure everything stays in sync). This isn’t a requirement, it just makes your life easier.

I think my suggestion would be to use the PC as a dedicated firewall, but you will need at least two ethernet ports for that (one to connect to the ISP router, and the second for internal network). This lets you learn network security and control the traffic that can actually get to your other computers. You could also set up KVM to start running virtual machines here. The idea with a VM is to keep services separate and isolated, so like one VM to manage security cameras, another VM to host a game server, another one to host sonarr/radarr/jellyfin… etc.

When you are able to expand, your second physical machine should be your NAS. Get your storage space started, share it over NFS or samba, and move your backup/security camera/sonarr VMs over to this machine for direct access to the larger storage space. Pay attention to system usage and move your VMs to balance the cpu/memory resources. Eventually you may want to get a third machine dedicated more for hosting the game servers, maybe a web server to view the security camera feeds, or whatever.

You mentioned backing up Wikipedia… Have a look at the Kiwix project, you can already get access to regular backups for a lot of information sites.

Why does everyone think the term came from Star Wars? I know it was used in steampunk before then, and google suggests it goes back to a 1958 article about robots. Sorry, not trying to be pedantic, just feels like a lot of people give Star Wars unjust credit for things they didn’t actually create.

Actually I AM that guy with a small font size and super-packed density. The more information on the screen, the faster I can take it in at a glance and find what I need. Sorry your brain doesn’t work that way, but less clicking and scrolling absolutely does affect my productivity and my idea of usability. For example, I find it highly annoying when a website changes to a larger spacing on a drop-down list and suddenly something I used to be able to immediately click on now requires me to scroll down several times to find the option I want. I’m not sure how that’s supposed to increase usability.

Heh I just ran into the invisible icons issue recently, for whatever reason I am no longer able to accept Teams meeting. Yeah that’s definitely a shitty thing. But more whitespace? In other words, less visible information on the screen which requires more scrolling or clicking to other screens? Sorry, that just sounds annoying and less productive.

What do you find “old-fashioned” about Thunderbird? Do you not consider an interface “new” if they don’t change it and hide all the common features every five minutes like Microsoft does? It’s an email client, you read your emails in it. How would you do it better?
