A computer case for mounting dynamic parts requiring media insert/eject space is disclosed. The computer case comprises a depressed plate which is formed in one part of the upper portion of the case to define an access portion for providing insert/eject space of the tray of the dynamic parts for loading a media; and a partition section which is vertically elongated from a bottom of the depressed plate for providing a mounting portion defined in such a way that the dynamic parts are installed in the portion that is the remaining upper portion of the case corresponding to the access portion, wherein the partition section serving as a boundary between the access portion and the mounting portion has an aperture for insert/eject of the tray of the dynamic parts for loading the media. Since the aperture for insert/eject of the tray of the dynamic parts is formed in the partition section, limitations to design for the front of the case disappear.
