A computer includes a main casing having an opening to accommodate a plurality of hardware components, a movable casing rotatably combined to the main casing to cover and uncover the opening of the main casing, and a stopper located on one of the main casing and the movable casing. The stopper rotates between a stop position, at which the stopper prevents the movable casing from closing the opening at a predetermined angle, and a withdrawal position at which the stopper allows the movable casing to close the opening. Thus, the movable casing rotatably combined to the main casing, is stopped from closing the opening of the main casing while a casing of the computer is opened to replace or repair hardware components, thereby preventing accidents.
