Dell Dimension 4700 case help

[Sir Loin]

My friend's HD recently died, and he wanted me to replace it with a new one, but I can't open his computer; how do I open Dell Dimension 4700 cases? It doesn't have any screws, I'm sure there is some way to open it, but I don't know how. Any help would be very appreciated.

Thanks,
Sir Loin

if it's the same as a demension 2300, there's a plastic tab on the back of the case, push the tab down then push the left side panel towards the back, this opens the case

Removing Panel Dell 4700

Kingcody it was so easy when I followed your instructions on removing
the side panel. It was really dusty but after the clean-up it runs as quiet as a mouse.
