Hmmm,
Given that the unit is optimised for front to back air flow I don't think you will go too far wrong with compressed air through the front (not that I'm endorsing it but have you seen the YouTube videos using Garden Leaf Blowers for this :-O ) and Henry or one of his industrial vacuum friends at the back to catch the dust, fluff and cruft that flies out.
There is a school of thought that says that you shouldn't disassemble the components as that potentially exposes the connectors that are usually seated together and haven't been exposed to dust contamination. However, I too would be slightly wary of turning the exhaust fans into wind turbines so I would at least remove those :-)
Let us know how you get on.
Cheers
Ian
