Although this has no pictures, it tells you a good method as to how to build it.

Here's one with pictures.

Use 5/8" melamine for what you're building.
1/2" will sag and will crack when you drill it, and 3/4" will be way too heavy.
Use 1.5" Particle Board screws.
They cost a few bucks more than wood screws, but you won't need to drill pilot holes (saves a TON of time).
I would use 1/4" glass (just plate glass, not tempered) because if you go any smaller, it's likely to break, and if you go any bigger it'll be quite heavy.
If you went with plexiglass, it'll sag over time, and expand/contract with the heat.
You can find 1/4" glass track at your local Home Depot for less than $10 for 4'.
Otherwise, for a 4'x2' enclosure, I'd have about 6-8 screws on the back of the cage, and 4-6 on the sides/back. Build the enclosure so that the top panel rests on the back and side panels, and the back and side panels rest on the bottom panel. It'll help distribute the weight of the wood.
