Insructions needed open cover on specifically sx270 optiplex

Lay the unit DVDRoM face down, and then slide the green 'thingy' (technical jargon) on the back of the unit in the only direction that it will go (should be a diagram on the case itself, to show how...) and at the same time slide the upper casing forward. I have one of these suckers, and it ain't as easy as it could be, but it will move!
Good luck!
