When I need a new one I'm just looking at what's available for a decent price (usually local on Mercari, sometimes eBay) and then checking the list of supported models for the not-ChromeOS firmware at https://wiki.mrchromebox.tech/Supported_Devices https://wiki.mrchromebox.tech/Supported_Devices If it's supported and I'm comfortable with the method for disabling write-protect then I pull the trigger. I usually install xubuntu, but on a couple models I've found Ubuntu/Debian based distros have some issues with the trackpad, but Fedora running XFCE works fine, so you may want to go straight to that if you're comfortable with Red Hat.
