The difference between that fridge and the kegerator is the freezer. You'll have to bend the freezer down and out of the way to make it work. It's do-able, but it would make me nervous doing it on a fridge I paid full price for.
If you do a quick search for kegerator conversions here, you'll find a host of model numbers that people have had success with, and what they had to do to make each one work. That might be a better bet.
