Oh yes, I recall the fun of that, from many years ago.
One of my favorites remains when we were prototyping our next gen of servers for some compute next to quite a lot of disk. We had a prototype design, but we weren't done testing it, and someone needed a grant spent _now_, so they bought that design.
Unfortunately, that was the Dell R715/R815 family, which you may recall, had some...unique performance characteristics, so we didn't go with those for the final model, but had to deal with the support of them thereafter.
