when we went through this in a previous thread, there was a hypothesis that
keeping it all in one case might actually have some noise, power and cost

more reliable than most external drive power supplies; i have a "drive farm"
and small form-factor computers myself, but i am open to the idea of Mac Pro
being a better choice for some people
I don't think so. When I changed from the G5 Tower with most drives
sited internally to the mini with external drives, the first thing I
noticed was how much quieter and cooler everything ran.
after first warning Larry (in that previous thread) that the Mac Pro might be
noisy, i did some lookups and found that power draw and noise have gone down
successively in the Mac Pros - here's one reference:
<http://www.barefeats.com/harper4.html>
basically, it looks like GPU cooling is the biggest noisemaker on the 2008
model in the test, and i'd bet Lightroom wouldn't kick that off; a different
graphics card (or fans on such) might also be an easy fix
i also recall that the Mac Pro internals were much improved over the PowerMac G5
now that i've finally replaced my 2007 MacBook Pro server (whose fans i had to
crank to 6000 rpm to keep the video card from overheating) i'm in the process
of replacing the fan in one of my dual drive cases to reduce the noise, and i
realize my Drobo has a fairly noisy fan too
