I did exactly what Gary suggests to clean up the power supply on my 
homebuilt octo-core machine (back when it was a dual core Pentium hi). 
Corcom is one of several brands - even the best costs only ~$10.  I had 
to do a little surgery on the IEC connector hole in my cheapo supply, 
but it was worth it!.
