I started self hosting many years ago when the company I worked for got new workstations and sold the old ones for next to nothing. It was a very powerful machine but I payed the price every month in electricity. I am now running a bunch of services on 2 mini pcs (each was about $250 USD) with laptop cpus and my electricity usage is way down (like 45 watts for both machines, router, and switch).
There will be a steep learning curve, but I highly recommend learning docker (especially docker compose) and how to setup a reverse proxy. The self hosted communities are very helpful and can answer more specific questions as they come up.
And able to be controlled locally with no need to talk to a cloud API. Fast, reliable, private, and future-proof.
