Getting a Sun Ultra 5 To Work

I am thinking of reasons why I would dismantle something. One obvious reaosn si to repair it, in which case I want to be able to reassemble it (or at least reusse most of the original parts). Anther reason would be to figure out how it works (or how it worked before it failed), in which case I want to keep it in as original as state as possible. It's a lot easier to work out how something works if the PCBs is in one piece, components are where they should be (and are intact so I can make measurements on them) and so on. I don;t think I ever do anything 'mindlessly'. I try to have a good reason for everything I do.
