I just transfered cases, from a Sonata to a Coolermaster pac-t01 (praetorian) and the seagate 120 sata drive I have is rather noisy. I didn't notice this while it was in the Antec case, but then again the Sonata was on the floor, whereas I put the Coolermaster case up on the desk. Now I have looked around for some silencer type products, my only issue is most of them are removable drive cases, which I don't want. The internal enclosures that I have seen, well they just dont look like they will work. I'm open for suggestions if any of you have used some products that may help.
