A casing for electronic, heat-emitting components, has a front provided with an ornamented bezel. Instead of a conventional ventilation grill in such front bezel, the bezel is bowed outwardly relative to the front edges of the sides of the casing. Ventilation is provided through the gaps between the back of the bezel and the front edges of the sides. The upper portion of the bezel may be formed with an opening to receive a media bezel having openings therein for removable disk drives, floppy disks and the like.
