I do see some nice glass display cases online, however, I have conceded that I neither have the room, nor the budget to spend on such a way to display my collection. I envy those that do. Still, I got a really nice custom build shelf in my room for my Titans. It is made of wood, and open, and yes it needs to be dusted as do the toys, but it's still pretty cool.
IKEA is also pretty versatile. Perhaps if there is not one glass cabinet that would fit Trypticon, sometimes they can be attached in some form, usually by some sort of bracket system, to make a larger display cabinet. I have three of the large IKEA bookcases, plus two of the slimmer ones all mounted together in my Livingroom for my media collection and books. Some have doors, some do not, but it really looks like one large unit despite being made up of several different ones.
Also, one way to reduce dust since I cannot put doors on my custom shelf...If you take some thin plastic, (for example a cheap dollar store shower curtain), and cut it to size and lay on the shelves, that will reduce dust. Some even put thin towels on the base of their shelves as well.
