OK, one more quickie (Woo Hoo, I'm having a quickie!!):
I have not been able to determine how to get the "other" side of my case off. I installed an add'l 2TB HD, and could only attach screws on one side when mounting it. It kind of fit into a "slot", so it's not drooping or hanging off-level.
Anyone think the two screws on the other side of the HD are important? If so, I'll pursue it before final installation! (still loading software titles today)
