It would probably be better with the board vertical, and with the 
fins on the heatsink vertical rather than horizontal. That way, 
there's be a much greater convective airflow and better cooling. With 
the original Mac, they managed to make it fanless by putting the 
power supply (and video board) vertically up one side - so the heat 
it produced generated convection and drew cooler air in the vents on 
the other side of the case and across the logic board.

Apparently cats weren't averse to sleeping on top of them :-)
