I’ve seen a couple of people say this as well. Scoop up an old Lenovo laptop and run Umbrel OS. The main benefit here would be the removable battery.

I can recommend Hp & Dell business models too. Stay away from home consumer devices and you can expect some longevity. Also, stick with a model that has upgradable ram/ssd instead of scraping the bottom of the barrel (like a chromebook).
Also, I’m shying away from umbrel in favor of start9, but I’m experimenting with Nix-Bitcoin. Such a pita, hope it’s worth it. Pretty sure it will be, but not for the fainthearted.
