A computing device, the computing device comprising: computing device housing which is affixed to a first assembly portion; and a computing display which is affixed to a second assembly portion; where each of the first assembly portion and the second assembly portion include a platform and a plurality of assembly joints extending from the platform, and each assembly joint comprises: a nose forming a terminal end of the assembly joint; first and second interfacing sides extending from the platform to the nose; and a tunnel running through the assembly joint from the first interfacing side to the second interfacing side, each of the first and second interfacing sides defining an opening (212A, 212B) to the tunnel; where assembly joints of the first assembly portion are sized and shaped to cooperatively interface with assembly joints of the second assembly portion, such that tunnels of each plurality of assembly joints collectively define a cable-routing channel, the cable-routing channel comprising at least one bend, when the first assembly portion is mated to the second assembly portion; and a flexible cable routable through the cable-routing channel to prevent separation between the first assembly portion and the second assembly portion. computing device housing which is affixed to a first assembly portion; and a computing display which is affixed to a second assembly portion; where each of the first assembly portion and the second assembly portion include a platform and a plurality of assembly joints extending from the platform, and each assembly joint comprises: a nose forming a terminal end of the assembly joint; first and second interfacing sides extending from the platform to the nose; and a tunnel running through the assembly joint from the first interfacing side to the second interfacing side, each of the first and second interfacing sides defining an opening (212A, 212B) to the tunnel; where assembly joints of the first assembly portion are sized and shaped to cooperatively interface with assembly joints of the second assembly portion, such that tunnels of each plurality of assembly joints collectively define a cable-routing channel, the cable-routing channel comprising at least one bend, when the first assembly portion is mated to the second assembly portion; and a flexible cable routable through the cable-routing channel to prevent separation between the first assembly portion and the second assembly portion. a nose forming a terminal end of the assembly joint; first and second interfacing sides extending from the platform to the nose; and a tunnel running through the assembly joint from the first interfacing side to the second interfacing side, each of the first and second interfacing sides defining an opening (212A, 212B) to the tunnel; where assembly joints of the first assembly portion are sized and shaped to cooperatively interface with assembly joints of the second assembly portion, such that tunnels of each plurality of assembly joints collectively define a cable-routing channel, the cable-routing channel comprising at least one bend, when the first assembly portion is mated to the second assembly portion; and a flexible cable routable through the cable-routing channel to prevent separation between the first assembly portion and the second assembly portion.
