Lol they can be tricky, denali. If it's the same as my Presario, take off the side panel. Underneath the hard drive bay you'll see two horizontal plastic tabs near the bottom of the case) and one vertical plastic tab (closer to the bottom of the hard drive). Push down on both horizontal tabs and at the same pull across on the vertical tab. At the top of the drive bays there is also a green plastic tab, push that in and it will release the top front of the case. I hope you understand those ramblings.
