The iMac obviously doesnt have the airport card/adapter installed and to get both of those off Ebay would be about $100 I think (or last I checked). Found an airport basestation for $30 but didnt know if I could use this in lieu of a wireless card. Can I wire it to the iMac and then use that to connect to my wireless router and get the iMac online? Dont want to buy it and find out it wont work like this. Thanks.
