I know that Rob (nosterbor) keeps his massive collection in 5000 count boxes. He has close to 30 of them...stuffed!! Every card is in a penny sleeve and topload. Almost 30,000 total cards are in year order alphabatized by manufacturer just like a list. He does have some cards in screwdowns, but not many.
I would not like it his way because it would be very difficult to find anything and you couldn't really look at anything conveniently.
