A computer includes a lid defining a lower edge. A hinge is connected to the lid along the lower edge. The computer further includes a base having an upper surface and a keyboard disposed on the upper surface and defining a back edge. A mounting assembly is connected with the base between the back edge and the keyboard. The mounting assembly has an attachment feature that moves along a translational path in a direction between the back edge and the keyboard in a manner that is constrained to rotation thereof. The hinge is rotatably connected to the lid to be rotatable with respect to the base. The hinge is rotatably affixed with the attachment feature such that rotation of the lid drives rotation of the attachment feature, which drives the movement of the attachment feature along the translational path, moving the lower edge of the therewith.
