Other people with these requirements may want to look at HP Pro and EliteBooks, if they're willing to put up with dubious screens (they're fairly OK for coding work, I guess). They're repairable in that HP has repair manuals on their public site, complete with disassembly instructions and part numbers. Never had to replace anything, so I don't know how easy it would be to actually source the parts. Most importantly, they are also one of the few to have AMD models without any soldered RAM, and they don't insist on HP branded RAM either. Linux works great on these. The worst I had was an older ProBook whose fingerprint sensor was unsupported. On my current one, it works 100% under Linux, while on Windows I can't get the webcam to work.
