The biggest question would be whether the coolant coils run through those shelves, in which case, bending them down without rupturing the coolant lines might be somewhat fiddly work.
Otherwise, yeah, what RM-MN said – slap a temp controller on it and black out that big glass door, and you should be good to go.
You probably can't rely on it without a temp controller – if its thermostat even goes up to fermenting temperatures it all, it probably won't keep them in as tight a range as you'd like.
