HP 2100S Power Supply Disassembly Tips

Hey all --

I've had this HP 2100S mini sitting on the bench for a bit, waiting, and I
wanted to go through the power supply and test/reform the capacitors this
past weekend.  The processor service docs cover getting the supply out
(which is slightly cumbersome) and I have that step done.  But neither the
processor docs nor the power supply service docs seem to cover how one
disassembles the supply itself.  (Has a really thorough guide to how the
thing works though, that I'm hoping I won't actually have to use anytime
soon.)

There are a lot of parts in this unit, and I'm not seeing a method to the
madness.  The capacitors are fairly easy to *get to* but actually removing
them for testing / replacement seems to be another matter entirely.  Anyone
out there done this before and have any advice?

Thanks!
- Josh
