Better of asking in EOF forum, extreme systems, and others more involved in phase change cooling.
most people going into this area shouldn't worry about size of compressor. Compressors size is important but it is related to what idle and load temps it can produce which is the main factor people look at when chossing compressor. So what temps do you want to see? Smallest setup is 1/3 midtower but I think optimal size is AC unit.
You can make it work but the temps will be around 0c-5C at idle and positive under load.
Better off puttting that amount of work and energy into a better AC unit or bigger setup for another $100.
