Noise Control Stealth Tower
Ben writes: "I have just reviewed a really innovative case. Noise dampening kits have been available for some time, but I think this is the first solution where the manufacturer has done something to combat the noise coming out of the BACK of the case! With its whisper box, the Noise Control Stealth Tower finally solves this problem" Update: 06/06 21:02 GMT by T : Ben points to this mirror, too.
I have moved my very noisy server into a kitchen closet that previously held a small refrigerator. So it has a power outlet and is well ventilated. No more noise in the bedroom (at least from the server ;-). And buying wireless LAN equipment to connect the server to my laptop costs less than the quiet case in the article.
