A good amount has been said (PC,servers, bike)

I think my tool box wrap it all up. With it I fix all the above and many more. I think i open it every day or so.

When I don’t ave the right tools at home there are cooperatives here that rent them for super cheap and teach how to use them too.

You can get really cheap stuff on second hand market especially if you’re OK taking a bit of time removing rust etc.
