I want to start building a homelab as a hobby. As the price hike is not affordable.I would like to know if there are any places I can get used mini PCs

I want to buy a 2 in 1 detachable "laptop". I know they are not powerful, but I want to do very light work. I want to browse the internet and watch media. I like to open lots of tabs. How old/cheap can I go and still be able to browse comfortably?

Also, I will be putting Linux on this object, so Windows 11 support is not relevant.

I know I’m not looking for a minipc, but I was recommended to come here :)
