Do you plan on converting the existing power supply to fanless, or are you going to purchase a new fanless power supply?
I may have to replace the power supply with a fanless model. The entire PC doesn't need alot of power to run so I can probably get away with a small factor 100 watt PS unit once I change the hard drive to a CF or laptop hard drive and no fans. I'd very happy if the entire thing runs under 20 watts but not likely due to the PIII. Lucky it's not a P4, power hungry little beast.
