Case Damping for Dell 960

[windmiller]

I've got a Dell 960 Small form factor and am installing a 2.5 drive in it to reduce the noise but wanted to take it a step furher and look at some additional changes.

I wanted to get any suggestions for material to use to muffle noise coming out of the case. Like a material to adhere to the walls of the case.

Also wanted to see if any other 960 owners have made any useful changes.
