I’m guessing they were the old upgradeable ones or that they didn’t have significant need for memory or internal storage. Those are the only use cases where Macs make financial sense any more. On newer Macs you can attach external storage that’s as fast as the internal storage so you don’t have to pay the 10x uplift on storage prices at least. I’m still running the last version with upgradeable RAM and have all the storage external.
