Hi, I have a mid-2007 iMac that doesn't work anymore. The hard drive is dead and the on/off button is dodgy as it fell off and only works with a lot of persuasion. I have since bought a new Mac Mini which I love, but don't know what to do with the old iMac? I thought about getting the dead drive replaced with a flash drive and if the button can be fixed then it would all work fine again. Is it worth trying to sell it?
