No idea what the big deal is about....  ;)

I just fire up the PDP-11/73 (RL02, RX02, RD52x3,), then 
Microvax-II/GPX, Then the PDP-8f....


The 11.73 has fans in the RX02, BA11 box, Rack back door near top and 
then the RL02 spinning.
The PDP8f has two very high volume fans.
The only thing I have that's close to that is the homebrew S100 case 
with two 120cfm fans
that blow across the boards and a pair of 8" shugart drives (with fans 
as well).

Warms the room well and makes the power meter spin pretty good too.
