A computer front bezel assembly includes a panel (10) and an access door (30). The panel defines an opening (12) therein. A securing tab (14) protrudes from the panel. The access door is slidably attached to the panel. The access door includes a shielding board (31) and an extending board (32). The access door moves up to cover the opening. A resilient engaging portion (326) is formed on the extending board for engaging with the securing tab. An expansion slot (321) is defined adjacent to the engaging portion for providing resiliency to the engaging portion. When the sliding board slides on the panel, the securing portion urges the engaging portion to deform for engagement/disengagement.
