Well I stole theKab idea and mounted my hard drives like this
As you can see I have two mounted with some ant vibration screws. Seem to work real good to quiet down the drives
Use to keep my HDD in the IcyDock, while I love the function of the dock and plan to keep it for easy file transportation it turned out that the hard drives where just to loud for 24/7 use. Now that they are hanging the noise is i'd say half of what it used to be. My 3tb Seagate is still a touch to loud for me. Gonna look into more ways to silent down the 3tb drive.
My only worry now is if a pump/res is gonna fit in the space between the back of the sock and the side of the HDDs. I'm also going to have to mount it right into the PSU, Hoping the PSU case comes off easy so I can get a look inside and drill a hole for mounting the pump/res on it without hurting it.. Plus I wanted to use the EK pump/res which doesn't come with a floor mount, only a side mount. I know the BitsPower unit comes with the floor mount but I'm real keen on the EK unit. Dunno what ill so for it yet, ideas?
