There are some who repurpose some Ikea-stuff as server racks: https://duckduckgo.com/?q=ikea+server+rack&iar=images&iax=images&ia=images&iai=https%3A%2F%2Fi.pinimg.com%2Foriginals%2F81%2F84%2Fab%2F8184ab11849051f4fa0f66f50b0ac97d.jpg
Yes, github actions. Or maybe checkout github pages? As long as your website doesn't need an SQL-database, it'll work and will be free
Bwa, we've had worse ;)
Yeah, but there is no button to remove all of them at once. And the next time you'll visit the site, they'll just get installed again - so I don't think it is very useful to delete them.
