I shall do so. The control unit for the compressor on the expensive models is actually just a PCB that has some options on it. I still have plenty of room in the case for a couple PCBs, so I should be fine. My dilemma is...should I purchase the ChillControl and retrofit it to the compressor, or should I make my own chill unit? The ChillControl is quite expensive, and I don't know if it would be worth it. Also, I just believe that Chip-Con and Asetek didn't want to go to the effort of selling separate components, so they built it in a good-looking box and sold it as a single unit. They probably could have made it inside a normal-sized case like my PC-60 had they wanted to.
