It seems the hardware change will activate it, while the motherboard swap or CPU adjustment might be necessary due to the underlying hardware configuration.
Only the motherboard matters. Swapping an SSD and reinstalling Windows on the same board should work again. Perhaps without using a Microsoft account and on a board without built-in BIOS keys, it might reactivate. Even then, it should be straightforward—just insert the key and click activate. @FatRambo45 You're all set. A GPU change won't cause this to fail, and even if it does, you can easily get it back online.
