Question : Problem: Remove front cover from Dell Optiplex GX150 tower to allow me replace on/off switch

The On/off switch has failed in the Dell Optimplex GX150 tower. I think I need to remove the front cover as the switch is behind the housing with holds the all the driver Hard disk and DVD rom and this appears to riveted into the PC frame. I have asked Dell and the Philipino lady was helpful but not knowlegeable. So I would appreciate and pointers on how to get at the on/off switch.
