A computer having a chassis having an opening for access to an optical storage drive unit. The optical storage drive unit is actuated by a button attached to a door on a front cover of the computer. The door is perforated by a hole enabling a user to push this button, which either directly pushes the operational button on the drive or pushes a linking part that then pushes an operational button on the drive to open the door and extend a tray out. If, for some reason, the button on the door is not aligned well with the button on the drive, only the door needs to be replaced as opposed to the entire front cover or the entire chassis.
