Does the rear mounted fan exhaust out the back or does it pull air in from the back?
I am planning to get another HD DVR to replace my other SD Tivo unit and want to get the HR21 series.
The reasons I ask are due to heat in my cabinet with my HR20-100. The temps are ok (109-115) but I liked the way my old SD DTivo unit blew the hot air out the rear of the cabinet keeping it cooler inside the cabinet. I find the bottom mounting of the fan on the HR20 to be a less efficient way to cool. It's like it just blows and recirculates warm air, not pulling cool air in and expelling warm air out.
