I've just been looking in to this as I've got quite a lot of older hardware that'll be fine for running some websites lying around.

My ISP has a static IP option for £5/month, but I reckon I can save £30/month+ on server costs even before any rises.

Ofc it does mean I have to do my own sysadmining, but a combination of my general knowledge + an LLM should make that relatively easy.
