Original Apple Top Cover for the beige Power Macintosh G3 Minitower. This panel is held in place with three tabs accessed through the drive bays and slides to the right (away from the green button). To remove the top panel, first remove the rear drive carrier (over the power supply) and the floppy drive. While applying slight sideways pressure, push back the front most tab, then push forward the centre tab. Lastly, push forward the rear tab which is behind the drive ribbon cables.
