I have no room where I'm currently living and I had both options of putting my entire collection in the attic or the basement. With the elements in mind, there was no way I wanted to jepardize everything. I have all my carded figs in Star Cases too, but I put them all in huge thick flower boxes - I heard issues about the "breathing" thing so I took this route.
If you have the space in your home, then by all means it should be taken advantage of, but I'm leary of the attic/basement issues - insects, rodents, heat, humidity. I since decided to go the expensive route by putting everything in a climate controlled storage unit to make sure everything stays nice and dry. I take a peek into various boxes every few months or so and so far there's been no problems - not that I'd see one arising.
My stuff has been in storage for over a year now. I won't boast about the size of my collection, but everything has been nice and kosher.
Just my 2 cents...
