that's the whole setup. i actually have two cages put together, and i moved the little plastic clip things to the left side of the top part only, so that i can open the whole top like a hinge. also, i covered the front, sides and top with 1/4" mesh to keep them from getting out (1/4" is what i had in the shed, but soon i'll be getting 1" and redoing the whole thing. i don't like not being able to pet them through the cage.) oh, and i took out the tubes, because all they did was make them filthy and proceed to wallow in the filth. i could be cleaning up all day and still not keep up with it, so i just took them out.
for the top shelf (on the right), i took a wire shelf i had from something else and used it to hang one of the shelves sideways against the back wall. the green basket is a litterbox. in the corner above that is one of those plastic balls that hamsters like to run around in, tied to the side. on the left are some hammocks of various sizes, and the "pool" (just a plastic bin with maybe an inch of water in it, to cool down in. yes, they use it.) that red ball hanging from the back has fleece scraps in it, which they can take and use wherever they see fit. below that is a litterbox, a treat bowl and a water bottle.
the bottom has a shelf for food and another water bottle, and a "bridge" made from one of the ramps that goes across to the bottom shelf, which holds a small bird cage with the door tied open, with another litter box inside. below, there's another hammock and towels and cardboard. the girls don't spend much time down here. they just come down to get the cardboard they want and bring it back up someplace.
I think I have the cage you're talking about, although mine is blue.
That was my very first set up, before I was prepared for it, hence the complete unawesomeness. I don't have any pictures of my later, better set ups. But this next one is the half-sized set up I made for Rokk - he's much more comfortable in this smaller cage.
That's also an older one - I've taken out the wheel since it wasn't stable enough for him to use much (he's too heavy for that flimsy thing) and put down towels and a litter box instead. I also put the two upper shelves together to make a bigger level, so now he actually uses the bird perch as a step to get up there.
