Are you talking about individual cases, or a large, wooded display case?
I keep my figures in round plastic tube cases, their file cards in those flat plastic protectors and I have them all in some nice wooden cases I made.
If youre talking about a large display case/rack, just get some lumber and make one. If youre talking about just the figure, there are really only a few ways to store them that I know of: Either the round tube cases or the plastic box cases. Neither looks great but the boxes look cheaper than the tubes in my opinion.
