If you want to host something on a Raspberry Pi, you should consider using literally any other piece of hardwarelocked
There are a lot of reasons not to give them your money. They're assholes to the maker community and they openly talk shit on a lot of their customer base. That's beside the point, though, really.
It's just not a spectacular option for hosting. In order to get a Rpi competitive with even the shittiest laptop from 7 years ago, you're going to end up spending more than you would spend on a decent laptop from 7 years ago.
If it is a computer that turns on, it will likely function orders of magnitude better than an Rpi and won't bind you to ARM architecture. My entire hosting setup was pulled out of a recycling pile for free. Install ubuntu/ubuntu server and enjoy yourself.
If you intend on spending any amount of money on this hobby, I cannot express enough how much I recommend against any of that money going toward a Raspberry Pi.
EDIT: A lot of you seem to be reading this as "Raspberry Pis are all nonfunctional" and getting mad about it. Don't do that.
Edit 2: Good to see that all the stupid parts of reddit made it here
Yeah, power consumption is never talked about enough when talking about that type of hardware. I do have an old PC I could use as a server, but I don't need more heating at home. Mini-PCs are cool, but how cool are they?
But anyway, I haven't been able to buy a RPi at decent price in years, so 🤷🏻♂️
You can use a thin client PC, which is usually uses <10 watt. Pi is even lower though, usually <5 watt.
