As a ready reckoner, 2 1.3GHz/3.0MB Itanium2s with 1 PSU, 8GB of RAM and

something you want to try running in a confined space on a summers day! 

2x rx2600 1.5GHz/6.0MB with dual PSU, 16GB RAM run here in my basement.
They are, for their size, the fan-noisiest of the boxes.   I have a rack
with 2xDS20Es (dual PSU) and 2xDS40s (triple) which make significantly
more noise at first power up but then the volume subsides.   There are a
number of other things running here as well.   In winter, my basement is
a comfy 76F (25C) without air.   In the summer, unless some appreciably
long heat-wave hits, these run and don't tax the 3ton air-conditioner.
The electric bill, of course, heats me up when it arrives.   

FWIW, it was incredibly quiet and COLD in my basement for about 10 days
late Oct. and early Nov. post Sandy without all of the space heaters.
