...in a regular iMac
Apple should go for it. The increased thermal output would allow desktop class GPUs in the iMac, and faster CPUs. I don't see why apple wouldn't do this. I can't imagine the new cooling architecture would add significantly to the cost. The only thing I could see holding apple back is their desire to keep power consumption low and also maintain a distinction between a regular iMac and an iMac pro.
