Hmm, there are pros and cons to this setup.
Cons - the kegerator is set up for a commercial tap. Most homebrewers use old Soda kegs, which use different fittings. You would have to buy the correct fittings for Corny kegs and install them. I'd also run new lines. Who knows how bad they are. Not sure how big that fridge is, but fitting 2 corny kegs MIGHT be a tight fit. Looks like you might be dealing with the compressor hump in the back of the fridge too. That guy got around it with the rack and short commercial kegs. You might not be so lucky with cornies.
Pros - Hole is already drilled for the tower. Thats a pretty big plus. It already has 1 tap and would probably be pretty easy to install a second one.
