All these readings were taken to judge how good the airflow management of the SFF is. The better the airflow around the casing, the lower the difference between each of these temperatures would be. If one spot is very much higher than another, then that means that air is not circulating too well at that hot spot.

A typical SFF usually displays a roughly 20C temperature difference (temperature delta) between the internal air temperature and the ambient air. We see that this seems to apply to the ZMax as well, even though it is running 1 processor and 1 video card more than the common SFF. This is exceptionally impressive. No wonder the system runs as stable as a rock.

We see from the measurement of the 3 sections of the internals, the stalest air is the portion in between the first and second video cards. These 2 cards are literally side by side. The 7800GTs are by no means cool-running cards and being sandwiched in-between them and in a tight SFF, I am not surprised at all the temperature probe reads 10C hgiher here than the rest of the areas.

Tbe Casing back is also quite hot. IWILL designed a large part of the whole casing to help with the dissipation of heat. So the aluminum body actually acts as a large passive heatsink. If we solely relied on the rather silent fans on the power supply and the copper towers, I'm quite sure there is a high chance the user would run into heat issues.
