I’m planning to build a computer primarily for programming and want to ensure it’s upgradeable for the future. and Hardware with opensource drivers support.
I have a question, what are you exactly seeking to repair?, like if you have a good working laptop, and if it gives good performance, then there may not be much need of repairing. One of the reasons for getting repairable hardware is that they last long, like I have laptops which are 13 and 7 years old, and they both “work”, batteries are dead, and replacements are not good, but other than that fine machines. If your laptop is not very flimsy, you may not even need an upgrade for a long time.
