Hi, one of my Dads friends has just given me an old iMac, saying that the hard drive is dead. However, I am not sure what model it is. I have taken a look around but nothing on apple-history seems to match what I have sitting next to me. All I know is that it is puprle, has two firewire and two USB ports on it and a slot loading CD drive. Does anyone have any idea about what model this could be? I need to go and replace the hard disk on it but I am not sure which one to get, I know that it will probably only be ATA 66, but that should not be a problem as it just means that the drive will run slower, right? Some people have said that I should not put a 7,200 rpm drive in there as it might be a bit too hot for the iMac to cope, is this correct? I was thinking of putting something like a 120Gb drive in there and then putting a better OS on it (I was given what seems to be the OS 9 disk with it), but do have a spare copy of OS X 10.3 which I would like to put on it if it is fast enough, which I am not sure about as I do not know which model it even is. Anyway, thanks for any help you can give me.
