I used to do this as well and this is fine if you're able to source cheap power. But I'm in the UK, electricity prices are insane and I can't afford to run this kind of setup any more.

it's not unmanageable to do if you have plentiful and cheap access to area that can see the sun. My 'vintage' computing collection got a lot bigger when I switched to solar.

a big ask in most of the UK, though.
