want to set up the snake enclosure right
 

Hi,
New to the page but been doing a lot of research. The snake I want will be around 5-6 feet as a adult is projected (Boa). I want to make sure it is set up 100% right. It looks like I will need at least a 6x3x3 enclosure. Then I would like to know what thermostats are recommending heating source interior should have. I am 100% about getting a snake and I want the best for it, Just don't want to make rookie mistakes by doing what is cheap or easy.
could any of you show me your products or set ups.
