Unfortunately my cube is in constant use hence I can't unplug until business finishes, but.... In principle could the fax card be removed if it was not being used? Or is it an integral part of the cube motherboard etc? The reason I ask, is that my Powerlogix 1.2ghz upgrade arrived this morning I have a multifunction printer/fax/copier/scanner If the card is remove able then it should only help in terms of heat management etc? Any Comments BTW big thanks to Laurie OWC came through for me and shipped the upgrade to the UK John Guy
