egpu with a late 2012 MacBook Pro A1278

Hello, I am just wondering if anyone has used an egpu with a late 2012 MacBook Pro, as I am thinking about doing it, I haven't got much of an idea on the graphics card I want to run, probably a high end nvidi, but was looking at the bizon box chassis. So my question is has anyone used this chassis or simila, how easy is it to setup and what are the improvements like? Thank you in advance.
