Regarding the noise reduction, is it the idle noise or the seek noise that's gotten reduced?
I didn't have a problem with the idle noise. Now that you asked it, I've put my ears near it and I can hear the idle noise, but it's not disturbing. Or maybe I tought that's the noise from one of my fans I can't really tell. But it reduced the seek noise considerably. So it's worth it, I think.
Thanks for the tip, man. I'm gonna try it in my P180 and see if the silicone grommets in the lower drive bay do the trick. Otherwise I'll pick up a Scythe enclosure and suspend it with rubber wires.
