I'm surprised to hear power supply and case are the biggest issues since those are needed by everybody. What keeps them expensive?

  Economies of scale, basically. Your options for a case are to go full-custom, which is expensive in small volumes, or to go semi-custom, which involves buying a case and having holes machined, which is expensive. With power supplies, you probably should buy off-the-shelf, and in small quantities that is going to be relatively expensive. I've never seen the case and power supply dominate costs on any of the designs I've shipped, though. The poster might have very particular power requirements. Some folks also get hung up on how much cable harnesses and connectors cost. I think it's because they conceptualize the design in their mind without them.
