    I want to replace the HD in my Mid 2011 27" i5 iMac with an SSD. All I want to do is replace the current drive not add a second drive. All the guides seem to be about adding a second drive. I don't want the noisy drive that's in there which is just stupidly slow these days.

    So my question is what do I need? I want to add a
    512GB Crucial m4 2.5-inch SATA 6GB/s

    What else do I need? Do I need the cable people seem to be buying on Amazon?

    Just ordered one myself from B&H. Since you have the 2011 all you need is the 2.5" to 3.5" adapter. I would get it from OWC, here this one is made so you won't have to stretch out any additional sata cables, should plug right in just like you're old drive.

    I just got done upgrading my 1TB WD Black edition HD that came with my Mid 2011 iMac with a 2TB SATA6 7200rpm HD, and adding a Patriot Pyro 120gb SSD. It was a smooth install I followed the instructions from http://www.btobey.com/learn/imac-ssd-install.php. However, I had snow leopard on my iMac originally then I upgraded to ML thinking that when it was time to upgrade the HDs I could go back to snow leopard with a clean install! Man was I wrong?!!! I have Os X 10.6 and 10.6.6 and every time I try to install from my DVDs I get a panic kernel error that my CPU is not supported! And the person I purchased my iMac from never gave me any restore or recovery discs! Therefore if you are looking to upgrade make sure you have upgrade discs or something.

    SATA Data cable killed my Motherboard

    Don’t plug the SSD data cable into your motherboard!!

    I installed a kit from iFixit and like some others, my fans wouldn’t turn off. Then when I removers the cable and reinstalled the CD drive, my fans STILL won’t go off!!! Took it to a local shop and they confirmed, it zapped my motherboard and now the fans will stay on ad infinitum.
