I happened to find this site and though some people might want to take a look. It's dedicated to noise reduction for computers and has lots of cool tweeks for making computers silent, including silent fans, acoustic deadening foam, and these cool feet. They look like the ones that sell for much more in audio stores and sites. Also, some people may want to look at some of these fans to replace the noisy ones in those Carver and Panasonic amps (I think the Panny has a fan). It's called Quietpcusa.com.
Here is a link to the quietfeet isolation pads:
