Yes indeed, the Mirrored Drive Door units first came out very noisy.  
I do
not know all the details, but there have been some fixes with 
replacement
fans and with software controls over fan speeds when running OS X.  If 
you
seriously consider one of these, it would be best to double check on 
its
condition.
The original MDD's, known affectionately as the "wind tunnels" did 
indeed have noise issues. There were two problems, the fans in the 
power supply produced a constant whine and the main cooling fan was 
loud. If you booted into OS9 these did a great impersonation of an old 
vacuum cleaner at full power.   There was  a noise problem and at first 
it was not acknowledged as a problem. Apple though stepped up and came 
out with a power supply/fan replacement program which cured the problem 
for the majority of users. My Oct 2002 DP MDD sits on a desk less than 
3' away and it is now very acceptable. My windooze box makes more 
noise. All the units built after Mar 2003, and all of the FW 800 MDD's 
have the improved power supply and fans. For the ultimate in silence 
the German company Verax introduced their own solution in the form of 
two kits that made quieter still.

The MDD is a very good Mac, just had some growing pains with the first 
ones. Supports multiple optical drives, a horde of HD's, 2 GB of RAM 
and has three PCI slots.
