For a snake or leopard gecko you could certainly convert a coffee table into a functional enclosure. Heat pads on the bottom and either use tap lights or small low profile led lights for ambient lighting only. Its certainly do able. Jaydsr make sure you really really really want a cwd before buying one. They are not an easy animal to care for. Their environment is tricky to maintain and expensive to set up. They are high maintenance. They are not very tame and dont generally tolerate handling much. Some dont seem to mind it but for the most part they are more of a look at and obey their every demand type of lizard. Plus there is their nails to keep in mind-almost all cwd owners look like they cut themselves or lose fights with cats on a regular basis.
