Acousti AcoustiPack Lite 2 Layer Material Sheets Kit

I had high expectations of this product and whilst it did slightly reduce the level of noise coming from my PC tower case its value was more that it changed the tonal quality of the sound so it was less whiny and thus less irritating, I have tried other acoustic insulation packs and none of them do what they claim in terms of dramatically reducing the noise level of a loud PC. You are better off investing in quiet PC fans and this would probably be cheaper than the price of this sound-proofing kit.
