Make a Sous Vide using Raspberry Pi and Mathematica?

Hello, I am trying to make a Sous Vide using Raspberry Pi and Mathematica. I am in the process of collecting everything I need but am not sure which Pi to get. Can anyone tell me what model I need? (I am following the article posted by Liz Upton)
