Went to the SuperMicro pages but their board specs indicate two fan headers. Any examples of boards/cases that have no fans?

I have been playing with lower power, but not absolutely fanless

it cool with a large copper heat sync and the front fans. Of course
I will be attempting to put 8 Mini-ITX low power boards in this case at some point.
