Assuming about 500W of power draw (3 x 605W power supplies, but
typically 1/3rd of max rating ever hit on the power supplies, plus
different power based on number of CPUs, memory & drives). This may
be close to what I remember last time I measured one of these running,
which is quite some time ago. 

That should be about 366kWh per month on average.

The "average" price for power is about $0.11 per kWh, and is close to
what I pay for here in the midwest.

So, about $40 month to power this server.

The fan noise & heat output outside of a datacenter would be something
else altogether.
