Thanks, Ken! It's a Sterilite 4-drawer setup from Wal-Mart (~$18) on which I switched the order of the drawers (it originally had the two small drawers up top). I drilled holes (next time I'll use a soldering iron) for air flow, just one row until I could see how it held humidity. It turns out I should have done two rows, because the humidity is now perfect (52%) with the drawer pulled out 1/8" instead of snug against the frame. I got the floor temp right by adjusting the number of layers of newspaper inside.

To protect against escape, I put 1.5" of velcro to hold the drawer to the frame on each side, just below the drawer slides, which means I need to hold the top steady to open it without disturbing Snyder or spilling water. Under Snyder's drawer, stuck to the bottom, is a pre-fab heat tape UTH (~$15 @ Petco). Inside the drawer is 3 layers of newspaper, one heat rock box (rock is NOT in use but box makes a good hide), one ceramic water dish (~$2 @ Lowe's), one small stone water dish ($? had it for a while), one baked stick from the yard, one found hunk of quartz, and one decorative fishtank stone. Oh, and one digital indoor/outdoor thermometer/hygrometer (~$15 @ Wal-Mart).

There's room under the bottom drawer for a human-style heat pad, which I'll be buying this weekend in preparation for the snake I hope to get next weekend at the reptile show. The back of the drawer-thingy has a handle-hole which is great for running electrical cords through but has to be otherwise blocked from the top snake escaping. The bottom drawer also has two large holes under it suitable for running cords through. The sides of the drawers fit snug against the case, and the snake should not be able to get out that way. I do have a light above the cage and cycle it for photoperiod, but it's not bright inside the drawer, just enough to see.

Hope that was useful!
