While there probably are some enterprise uses that might justify replacing individual components, most do not. In our company people are issued a laptop and they can choose either a small/light portable or a larger/heavier laptop. They can choose a Windows box or a Mac. We are all expected to use Onedrive to store our files. After that, if anything goes wrong, they swap out the machine and give you a replacement. You install one drive to get your files back and reinstall your apps. The laptops then go back to the It department where if they are under warranty, they get credit for them. if not they are wiped and go to a recycling service. I know some companies don't buy their laptops but use a leasing service so failed machines just go back to the service and are replaced by another. No one is doing individual component replacement.
