A system that incorporates teachings of the present disclosure may include, for example, a set top box having a controller to present media content to a user, receive a message, and selectively cease presentation of the media content until after the message is reviewed. Such carrier can be a thick-walled capillary tube or other shapes. A plurality of perforations is defined through the transparent glazing for allowing outside air to flow through the transparent glazing into the plenum and substantially maintain the transparent glazing at the ambient temperature, thereby providing for higher thermal efficiency. Further, the method can include providing one or more conic cuts on the base of the rotor disk between the pair of dovetail walls of at least one dovetail slot.
