I called Apple and they were very unhelpful about which airport card is required for the iMac G5 1.6 Ghz. I found a bunch on ebay (A1126) but I think those are for different models. Thanks in advance.
I installed one in my old imac G5. Just go to ebay and buy anyone that says A1026. They all look the same. When installing it, after you snap it in make sure you connect the antenna wire
