Hmm...good point. I too get complaints about my system...when the downstairs starts vibrating I live in a house, but that dosn't mean loud noise is acceptable...

Well, for me, fan noise isn't too bad. I'm rather used to it. My server and main computer use the same, loud HS, and both are on almost 24/7. If it where my decision, I'd look around for a more efficient HS.
