    This appears to be a good idea. One of the first things that occured to 
me was to take the piece of foam rubber out of the fan slot on the left 
hand side of the machine and slap in another fan. Obviously, two fans would 
be twice as good. I mentioned this simple but brilliant mod to Gary Sanders 
n8emr@gws and he said "No". Here was his story. The early systems were 
shipped with two fans, but that caused air stagnation and hard disks were 
overheating and failing all over the place. So there is a reason you only 
get one fan, it is not because AT&T were too cheap to spring for a second 
fan. So judging from that and what I have read in this group, the tip seems 
to be: Go for a hefty AC fan and put up with the noise. Any suggestions for 
model numbers and sources? Or are all the 3b1 AC fans swapmeet specials.
