re: iMac RFI noise

I do not know about iMac RFI noise. I have a Mac Powerbook 1400, with a G3/233 Mhz CPU upgrade and this machine is incredibly quiet. I use it next to my HF rig and hear nothing. I also use it on 2m packet and have zero problems. I would be interested to hear from others regarding the iMac - I wonder if those translucent plastic cases are the culprit?
