Do you keep your mech lance/star boxes?

I've managed to build up quite the collection of mechs over the past couple years, and I have kept most of my mech boxes, too. I am starting to kind of run out of space.

The boxes are very cool, and though I like keeping them for their aesthetic, I also feel like I'm turning into a bit of a hoarder, and I'm running out of closet space that could be used for something like the actual mechs themselves, books, etc.

So do you keep your boxes? Do you think they'll have collectors value? Or should I just focus on the mechs and cards instead?
