Reminds me of a customer that had in their contract requirements GHz amount so after we won the contract we digged out some old P4 based Xeons (everything after for a long time had lower clocks) and they got their stuff ran on old junk because it would be breach of contact not to.

It was govt thing and they are required to put a new bid every few years and their bid was EVIDENTLY "just list what our current hosting provider has, we can't be arsed to spend months migrating infrastructure every few years", but the clever weasels in the sales managed to get them.
