If you can navigate your was through docs.hp.com, you can find these 
manuals (PDF):

    installing the hp Visualize workstation c100, c110, c160, c180 to 
c200 CPU upgrade (a4200-900xx)
    installing the hp Visualize workstation c200 to c240 CPU upgrade 
(a4200-90035)

at this excessively long URL:

IIRC, the main reason for the larger power supply in the C200 (& up) was 
to support the Visualize FX-6 graphics interface (which has 3 
PA-8000-based geometry engines & is not supported under Linux). I 
believe the board will fit and as long as the power connections are the 
same, it will probably work. But, there may still be hooks in the 
firmware to detect the larger power supply. I might know someone who can 
answer this, but it would probably take a few days.

BTW, the service manual for the C-xxx models are available on that same URL.
