Inside the Stealth Tower you will find wall-to-wall carpeting the likes of which you have never seen! Most of the panels are double lined with the noise dampening material, so the dampening effect should be much more profound than when I tested the Magic Fleece kit myself.
The large metal expanse with no fleece attached is where you install the motherboard and other components. Behind this tray is a double lined side panel
You can see the notch in the second layer has been carefully cut so that the side panel fits on snugly, fitting the case skeleton like a glove.
You can see that the drive bays, where normally a lot of noise escapes is extremely heavily lined with fleece. I am very impressed with the sheer amount of noise dampening matting used in the case - if you were to DIY a case of this size with the same extent of sound proofing, you would have to factor in at least two fleece packs - which would set you back over £80 alone from Chillblast.
Here is the inside-back. Plenty of spare PCI slot gaps, and space for an 80mm fan to be mounted. This is where 90% of the noise escapes in a regular fleeced case. Enter the whisper box!
