cooling systems

rack systems with integrated hvac do exist. as a general rule it cheaper 
to buy one or two large ac units and move air around as needed than it is 
to buy lots of small ac units have to deal seperately with the exhaust 
from all their little heat-exchangers...

there's a substantial amount of engineering that has to go into the 
thermal management in a 1u or 2u case that simply doen't have to 
happen in the desktop pc industry. even if you have sufficient cooling for 
the room you may still need dedicated airhandlers to move it to the 
right location for the rack with the nodes in them...
