Friend I have been dealing with this conundrum ever since I started collecting a few months ago!
What I do is keep all regular copies and a few limited editions sealed, BUT, I always open any big boxes with figurines and goodies.
In my opinion, the whole point of buying these huge collector's editions and PPEs is for the things inside. If you're not going to open all the figurines and extra content then you've just paid a premium to have a big, heavy box lying around.
I do however keep some steelbooks and relatively small limited editions sealed because of their rarity and they look too damn gorgeous to open. So I would defo keep a joel edition sealed. But something like a PPE!!!?? 99% of the beauty is in the statue so why would you hide it inside the box?
Just my two cents,
Aash
BTW, good luck on the giclees, I'm trying to find some that have been sold out as well. If you have any sealed stuff you want to show off, be sure to also check out sealed game heaven
