From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Old Thinkpads are your best bet, especially for linux support. I scored a new T14s gen 3 for $300 earlier this year, and like a year earlier got a T14 gen 1 for $200.
The Intel Thinkpads should have great support and upgradeable ram, the newer AMD ones sadly have soldered ram.
