Getting Cool With Peltier, Continued
The cooling unit requires a good deal of space inside the case.
The cooling system is easily located in the open case, as it takes up a relatively large part of the interior. The inclusion of the two Peltier devices came at the cost of additional 3.5" drives - as a result, the would-be fridge can only be equipped with two hard drives.
