Perhaps the article is a spoof, or late April 1st thing. Note these quotes from the "passive ventilation" part:
"In the absence of any air motion, hot air will build up in a pocket around each heat producing component in a cabinet." Hot air won't build up, it will rise - that's what passive ventilation is.
"your components will be cooled to some extent just due to the fact that the air is set in motion by any movement in the room." Indoor passive ventilation is warm air rising, not some one walking thru the room.
