You should also spin down the hard drive when measuring the power  
draw. I've tried to convince d.net that there should be a light  
client that gets all it's keys and logs results to a master node on  
the LAN. I used to run clients with remote mounted disks.

If it used as little as 1 watt it would cost about a million dollars  
in electricity alone to find the key using this chip. I'll bet it  
runs a lot hotter than 1 watt.

This is the primary reasons I stopped running the client. I still  
believe the hardware designs are useful for an educational exercise  
and a system needs to be set up so the implemented designs can be  
tested in the real world. But if it's stats you are after, why not  
just send your money to d.net and buy the stats? At 38watts/Mkey/sec  
and 10 cents/KWh that works out to about 3500 blocks per buck.
