Actually having many hard drives might cause much more vibration than fans...
I have a thermaltake case, with 9 fans... and 6 internal hard drives :eek:
Yesterday I disconnected all my fans (left the case open to keep it cool), to test if they would make a difference.
It didn't, 90% of the vibration in my case comes from the 6 internal hard drives, these really vibrate a lot, and it's a kind of cyclical vibration, comes in "waves"... It is quite easy to feel it with my hand on the case top, and it isn't quite "high frequency", it feels like it could indeed hurt the burn quality.
Is it possible to make my Plextor Premium 2 an external drive? How can I do that? Is USB reliable enough? (I also have a lot of external USB stuff connected, hard drives and all)
