It may go against some other sensibilities, but if you have only one place to put your gear, perhaps use some appropriate spacing/supporting items and place the 7100 on top of the 950 with 'free and clear' air above the 7100? Remeber the 950 needs a little airflow, but at least the 950 will not be bathed in pre-heated air and 'relatively normal' air would still be entering the 7100 from underneath, assuming you leave some space there.
