I'm considering a new dual G4, but I haven't seen anything from Apple on the sound tests giving an ISO 9296 number (sound pressure in decibles at user position [http://Silentpcreview.com has set a target of 20 dbl. at rest, but most machines run at more than that]). I've looked over the old threads here too and there doesn't seem to be more than ear to the case tests. Has anyone run across any objective lab results from Apple or any other source? Can someone tell me who is making the HDDs on the new duals? I suppose hoping for a quiet Seagate Barracuda V is hoping for too much. Does Apple have something like Dell's environmental info page? (see, e.g. http://www.dell.com/us/en/gen/corporate/vision_000_environ.htm. I'm hoping the dual G4s are as quiet as the Dimension 8250 now). I came across an outdated enviro page on Apple's site, but I couldn't find any decible information. Thanks.
