There's the German Thinkpad Wiki [1] which helped me choose a model, because they list every component/spec/variant there with all their hardware details, bugs and typical problems (with firmware versions that usually just need to be updated before you install Linux). (A quick side note: Current mesa has issues with Haswell and Broadwell CPUs due to the (now still) incomplete Vulkan migration. Just as a heads-up) [1] https://thinkwiki.de/ThinkPad-Modelle https://thinkwiki.de/ThinkPad-Modelle
