The PSU is up there so what do you need? Longer SATA-cables?
Vibration/sound is all the same here; the vibrations causes the sound. Suspending the drives gets rid of the vibration.
Forget about the HDD cage. Unless you suspend the HDDs on their edge like xan_user
suggest, there's not enough room there for a suspended drive.
It might help if you tell us more about your system. The obvious solutions are suspension in the 5.25" bay or perhaps foam bricks on the bottom of the case. But if you have a couple of ODDs and a bunch of expansion cards that might be difficult.
i am aware of the vibration/sound connection, just saying only the former is really a problem for me
well, here is how it looks:
this was a couple months ago, i've since bought a hyper tx3 and moved the hdd to the middle slot of the cage (that helped reduce the noise/vibrations somewhat). i feel like there's too many cables around for me to move it the hdd all the way up there, right?
a completely unrelated question, but maybe someone here knows: if my pc beeps twice on startup and i have an ami bios, this site:http://www.computerhope.com/beep.htm
says that's either normal or a parity circuit failure. what's the difference between that normal double beep and a "problematic" one? the system itself works perfectly fine, i am not really noticing anything out of the ordinary.
