I noticed a slight problem after installing the 1st fan.  I had the fan
in backwards, so instead of blowing the air out, it was sucking it in.  This
keep the power supply pretty cool, but the front of the UNIX PC was getting
warm (abnormally warm).  Make sure if you install the fans that they are
blowing out the back (Radio Shack label facing grill in back).

Since I had the PC open again, I took this opportunity to install the second 
fan.  I didn't get fancy and make it controllable by the LED.  The noise
is so minimal I though it might as well be on all the time.  The brushless
fans have a very low noise output.  I just tied the two fans together
keeping the polarity the same, and wha-la!  Now the system seems to be moving
air out very nicely!  Why didn't they stick with the two fans like the
older PC7300's?  Oh well!
