Hey guys, I have an iMac 21 inch 2010 model, the recently stopped working, when I turn it on i can hear the welcoming sound but theres a total black screen, I figured it could be the LogicBoard or the Graphic card thats the issue here, but repalcing those things would be extremely complicated and also a bit exspensive. So i had another idea, which I know sound crazy, but i was thinking about buying the same model from someone on Ebay I got one in sight for only 200 dollars. Then take the Harddisk and replace it on the ''new'' iMac, now my qestion is: would it be possible to repalce it, and then have all the stuff on the new iMac, including all the users etc? thats what im worried about, so if thats not possible i have to go to a specialist, who can move all my stuff down to a USB? Thanks.
