Start making rounds at companies near you. I haven’t paid for a laptop, desktop, server, monitors or ssds in nearly a decade. I pop in, ask if they have any hardware that they need to get rid of. Most companies have to pay to get rid of techology, most of the time their IT department is happy to offload tech for free. You just have to be fine accepting things 5+ years old.
After enough time and making friends with the c-suite, I have a couple companies that just ring me when they have stuff they want to clear out to give me a chance to grab stuff before they recycle. It reduces their cost to recycle, so they are more than happy.
I have used a number of distros over the last 15 years. Once I found one I liked, I stuck with it. I understand the package manager, some of the special features of the distro I use and I don’t really have time to relearn this every couple of months on new distros.
If I want a different “feel”, I change my DE. But that’s about it.
