i had a similar deal for about a year. problem was, the little part in the top of the fridge that was supposed to form ice, obviously never did, so it was dripping wet all the time. I constantly (well, when i was fermenting) had to wipe it dry. well after a year of use, i was going to move it, and discovered i hadn't dried all the water that formed, and it had leaked to the bottom back of the cabinet and was covered in mold. the back panel had warped and came off (i made my extra space using an old kitchen cabinet)
Here is the thread w/ pics of my old ferm. chamber

that first pic, you see where the fridge butted up against cab, that is where water at some point leaked out.
anyway, note to anyone doing this.. watch for water. am I the only one with that problem?
this is what I have now: a 5cuft. chest freezer w/johnson controller
