An apparatus includes a fan having a fan housing with guidance members extending from opposing sides of the housing, wherein the fan housing has a depth that is less than a height and width. A handle is pivotably coupled to the fan housing, and guidance tracks are positioned on opposing sides of an open channel. Each of the guidance tracks has a first track portion extending from a first face of a chassis in a first direction into the chassis and a second track portion extending from the first track portion in a second direction. The guidance members move along the corresponding guidance tracks, wherein the fan housing moves along the first track portion in a sideways orientation and reaches an operating orientation in the second track portion.

An adjustable riser cage retains varying length adapters. For example, the adjustable riser cage may support a short adapter card, a &#xbe; length adapter card, or a long adapter card. The adjustable riser cage includes a riser portion and an extension portion. The riser portion includes one or more guidance features and a plurality of first retention members. The extension portion is slide ably supported against only the one or more guidance members, and includes a second retention member configured to engage with a particular first retention member depending upon a length of the adapter card to be supported. The adjustable riser cage may be installed into a larger electronic system having a plurality of electronic components. The adjustable riser cage allows for increased access to the electronic components because the extension portion is not supported by external or non-integral support features that may block access to the electronic components.

An integrated circuit is disposed on a circuit board. A heat sink retention module includes a bracket, members, and coil springs. The members extend through the coil springs and corresponding holes within the bracket to attach to the board. A heat sink is removably installed within the bracket in a toolless manner, such that the heat sink comes into contact with the integrated circuit. The heat sink and the bracket join together to become a single entity that is permitted to float along an axis perpendicular to a surface of the circuit board. The coil springs are tuned to define a predetermined force at which the heat sink is pushed against the integrated circuit. The module can include a latch having tabs bent at different angles relative to one another to balance forces applied by the tabs against the heat sink while the latter is being installed within the bracket.
