Just wanted to mention that the power now stuff is cool. Lets the system run
at low speed, low heat, low noice ( my fan speed goes up and down as needed )
You can barely tell that my 3 AMD boxes ( all with power now enabled ) are
on when they are idle.  My office stays cool all of the time. When I rip a
DVD or do something that is intensive... the CPUs power up, the fans come
on when they everything goes back to normal when the task is done.
