Agreed. There are countless old models you can buy off eBay, drop in a new SSD and battery, install your distro of choice and keep using for several more years.

Almost all models of that kind have a lot of serviceable parts, for example replacing the thermal paste is usually easy and makes the cooling better than it was brand new. I haven't bought one myself simply because I have my own units that still work 10-15 years later. The screens mean they're dreadful as actual hands-on laptop experiences, but they're perfectly fine for home servers with built-in battery backup and management console.
