The cover comes off just like that, revealing a beautiful blue motherboard within.

There's a fan approximately twice the size of the new MacBook Air's fan on the top cover of the Google TV Logitech Revue.

The internal fan is attached to a nifty duct that directs the air flow across the CPU heat sink (located in the area shaded in red when the device is assembled) toward the vents on the side of the top cover.

Compare this to the fanless Apple TV that relies on conduction and natural convection to dissipate its internally generated heat.
