I just got another iMac off the ebay just for my project computer. I don't want to buy them an Airport card coz they're more expensive than the imac itself and I don't really need internet connection all the times. I looked around ebay again for wireless thing and I found this D-Link DWL-122 or exactly what this dude selling http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=45000&item=5782282311&rd=1 Are they really works on my imac? Do you have experience with this thing? Thank you very much and have a great weekend!
