I haven't seen him in a while, but I know a guy who was still using a Centris as his main machine even after it hit the decade mark. He actually wondered the same thing--how many of these are left?
My guess is that they are few and far between because...
1. As previously pointed out, the line was only produced for a few months in 1993.
2. Collectors tend to shy away from Centrises/Centrii in favor of all-in-ones (it seems people would rather have an SE/30 or Colour Classic than some modular 040 in a generic case) with the exception of LCs (a lot of people on here seem to love LCs), maybe the early Mac IIs, and Quadra 605s (hooray for feets!!!)
3. Some that are left may not be stock, I think Apple had a PPC upgrade for them.
4. I don't recall the Centris selling well. Lack of name recognition probably led to some people 86ing their Centrises/Centrii because they thought it was just some unremarkable Mac (even though we all know it's a good machine in its own right).
