Abstract: An electronic device may have electrical components mounted in an interior region of the electronic device. A housing may surround the interior region and may separate the interior region from an exterior region that surrounds the electronic device. Arrays of recesses may be formed on opposing inner and outer sides of the housing. The arrays may be laterally offset from each other along the housing. The recesses on the inner and outer sides of the housing may meet at passageways within the housing. During operation of the electronic device, air may flow through the inner recesses, the passageways, and the outer recesses to cool electrical components within the interior region. Lighting may be provided for the housing. Light-emitting devices such as light-emitting diodes may be received within cavities in the housing. Light guiding structures, diffusers, reflectors, and other structures may be used to help adjust illumination from the light-emitting devices.

Abstract: This application relates to hidden fasteners within an electronic device. An electronic device can include a top portion and a base portion that includes a housing and a cover attached to the housing by at least one fastener that is not visible through an external surface of the cover. Each fastener includes a receiver housing that retrains spherical components and a pin that can be inserted into an opening in the receiver housing. The pin is retained in the receiver housing by a force imparted against a surface of the pin by the spherical components, which are biased towards an inner surface of the receiver housing sloped towards the opening. The pin can be released when an external magnetic field from a magnet placed proximate the bottom surface of the receiver housing retracts the spherical components away from the opening, thereby reducing the force against the surface of the pin.
