I found this iMac on ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=190270727962 and if you go through and look through the sellers feedback, he happened to purchase possibly the same one from " 2ndturn " here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130264120133 and then went on to purchase new 2GB PC2-5300 RAM which is the same required for the iMac here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=300268998601 He says that he had to replace the glass screen so he might have gotten one from that other seller that had scratches on the screen and replaced it himself. What I am wondering is, is if he did do that, does it void any warranty that he claims it has left on it. I know that by opening up an iPhone it voids the warranty, or thats what Ive read and I did open mine up. Please give me some insight as soon as possible. I would greatly appreciate it.
