Glass aquarium type of tank or wooden with glass front?

I herd that the wooden one can pick up bacteria in the wood and its bad for the snake. I am curious on how its going to pick up the bacteria.

I am in the process of buying a glass terrarium already set up for my BP it has undertank heat pad with thermometer, and bunch of other goodies.

But I am curious if I should re-use my old tank for another BP or should I dispose of it. I will post a pic of it and if someone could please tell what I should do. Thanks
