I wasn't aware people actually purchased Mac Pros with great regularity. I don't know of a single person who owns one. The lack of customization, absurd cost, and plethora of superior competitors seems to discourage most people from this particular market.

I think Mac Pros tend to be purchased by organizations rather than individuals.

They are substantially more customisable than an iMac.
