Titan class figure storage

[philby]

Just after some thoughts on what to do with Titan class figures or "too big for my detolf" class figures. I have metroplex, fort max and trypticon sitting on a mantle gathering dust. i am almost certain to get Omega as well. Any tips on cabinets or storage? Taking shelves out of my existing detolfs won't work because then I need to put the other figures somewhere I can't just leave them out in the open any more even with regular cleaning

since myself and other family members have dust allergies i think my collection is starting become an actual health concern
