Don't they all have condensers? I know some are exposed on the rear and others are built into the sides and top.
Some small dorm room coolers use Peltier thermoelectric cooling. From what I have read in other HBT threads on building fermentation chambers, while they may work for ales they don't seem to reach lagering temps.
There are dozens of threads on fermentation chamber builds. What you end up with depends on what you need both in function and in size / looks, as well as price.
