anyone try adding an external antenna to the mac mini? i need to get a better signal on my new mini, but i don't really care for the third party usb wireless cards, so i'd rather try to replace the internal antenna with an external. does anyone know what kind of connector the internal airport on the new mac mini uses? is it mc card? if it is i'll try to pick up an mc card to sma cable. your input would be appreciated, thanks!
