A sliding mechanism and a swivel mechanism allow a user to quickly and safely access components of a computing system, such as hard disk drives, included in a chassis. A housing affixed to the chassis includes a tray, which is coupled to the housing by the sliding mechanism. The swivel mechanism also couples the tray to the housing and allows the tray to be pivoted about the swivel mechanism. For example, the tray may be extended out of the housing via the sliding mechanism, and the portion of the tray extending from the housing may be pivoted using the swivel mechanism to simplify access to components coupled to the tray.
