I’ve never done any sort of home networking or self-hosting of any kind but thanks to Jellyfin and Mastodon I’ve become interested in the idea. As I understand it, physical servers (“bare metal” correct?) are PCs intended for data storing and hosting services instead of being used as a daily driver like my desktop. From my (admittedly) limited research, dedicated servers are a bit expensive. However, it seems that you can convert an old PC and even laptop into a server (examples here and here). But should I use that or are there dedicated servers at “affordable” price points. Since is this is first experience with self-hosting, which would be a better route to take?
Servers are just really big computers. I started off with a Chinese Raspberry Pi clone, then upgraded to an old mac mini + mini pc + a cheap cloud server (VPS). As you can see, you can turn any old computer into a server.
The cloud is expensive but reliable. Having your own server is cheap but it will go offline with every network fault or brownout. If you’re serious about self hosting I suggest buying a UPS.
