I have kept original packaging for all my equipment except, as someone already stated, those things that cost less than $500. I don’t have room in my house (not even in my “junk room”), but I have a one car garage and I put the boxes out there. Yes, they take up some room, and I can’t park a car in there because of all the things I want to keep, but I think that is better than getting rid of the boxes. I have an attic, but I don’t want to risk rodents chewing through the cardboard to make their home. I think this question involves priorities, unless you truly don’t have anywhere you could store them.
