Has anybody done this and whats required?

Drive to an aircon-specialist and get it drained, then start dismantling!
Also don't let the system be open to ambient air for longer periods, plug pipe ends etc. directly.

Or you want it gone completely?

I think removing it completely isn't as easy as say.... remove all aircon bits & belt, find a new aux belt for a car that doesn't have aircon etc...

I think you also need a new alternator bracket IIRC.
