A collapsible shell cover for a computing device having a holder portion, an input device portion, and kickstand portion is described that is configured to support a computing device at a viewing angle in an open configuration and to form a shell cover for the computing device in a collapsed configuration. The holder may receive the computing device between edge members having support lips for support. The input device and kickstand are rotatably secured to the holder at opposing ends of the edge members. In the open configuration, the holder is positioned at the viewing angle, the kickstand is rotated for support at a rear of the holder, and the input device is rotated to extend outward from a front of the holder. In the collapsed configuration, the holder, input device, and kickstand portion are aligned in a common plane to form the shell cover for the computing device.
