Embodiments of the invention provide, among other things, computing carts with a storage compartment having a sliding work surface that selectively provides access to at least a portion of a storage space within the storage compartment. In some cases the storage space is defined at least in part by a storage chassis and a sliding work surface positioned over the storage chassis, with the sliding work surface at least in part defining a top extent of the storage space. In some cases a latch mechanism releasably maintains a sliding work surface in a closed position and allows movement to an open position when released. Some embodiments include a lock mechanism to secure a sliding work surface in a closed position to prevent access to a storage space. Strengthening mechanisms may also be provided to strengthen the storage compartment in the open and/or closed positions.
