Allow me to rephrase, then. I have personally upgraded PCs many times. The most common upgrade for me has been adding more disk space. Back in 1995, a 1 Gigabyte hard drive for $250 was just the thing for your new installation of Windows 95. The second-most-common upgrade is getting an employer-issued machine with a baseline spec and needing it to be a bit beefier. If you're running virtual machines or dealing with large datasets or analysing large heap dumps you might need some extra RAM; if you're doing machine learning you might need more disk space. The third-most-common upgrade is a better GPU. PCI Express means modern cards will plug into 10-year-old motherboards. Maybe your PC was just short of what you needed for that 4K display, or you'd like to play some newer games. Of course, if you're informed enough to do this, you're undoubtedly informed enough to know not to expect to upgrade these modern Macs.
