From what I've seen, sealed Duo's don't auction that much higher than non sealed consoles. Probably revolving around what TurboSwim just mentioned, about the caps leaking through the console. So I wouldn't worry about opening it up and loosing a fortune, because precedent sales (from what I've seen) have only sold for 1.5K'ish USD. While regular complete boxed consoles sell for 1K USD ish? So it's unlikely some idiot will bid it up to something insane like 4K, where u could then just buy a Duo modded to the nines and a nice steak dinner.
