A flue device for use with a computer rack includes an elongate body having an open end and defining a ventilation channel. The flue device further includes a coupling feature adapted to couple the elongate body to the computer rack. When coupled to the computer rack, the elongate body extends in a substantially vertical direction with the open end extending upward and is positioned to cover each of the respective vents to receive air from the vents and direct the received air toward the open end.
