I don't have any pics of large setups, I'm right about at the same stage as you, where I can use smaller ones at the moment. There are several pics within this forum that you can search for, though. The key is to use several variations of words in your search. Using the "plus sign" before a word means that the results will contain that word. (The plus sign is interpreted as code within posts and it won't show up, that's why I spelled it out instead. Use the actual sign when doing searches.)
I did a search for: (plus sign)monitor (plus sign)cage and got several results, including this one: forums.kingsnake.com/view.php?id=1184800,1184800
Here's a fairly recent thread that shows a person's enclosure: forums.kingsnake.com/view.php?id=1371993,1374049
There are plenty more photos, you'll just have to search for 'em.
One other thing, a lot of people line the inside walls with FRP (Fiberglass Reinforced Panels) that can be found at home improvement stores.
Have a good one!
