    Hey Everyone,

    I did a search but couldn't find any specific info as related to the 20" (late 2006) iMac..

    Basically, I do a lot of audio work with Logic and DP and I'm interested in replacing my 20" iMac's optical drive with a second internal hard drive.

    If anyone has any experience or insight regarding this, I would greatly appreciate your input.

    About 6 months ago, I did a DIY replacement of my iMac's internal hard drive (upgrade to 1 tb), so I'm pretty sure I'd like to DIY an optical drive / hard drive swap - that is, if it's

    1) Proven to work stably (thermally and otherwise)

    2) Not going to require the iMac's fan to be running faster/louder than normal

    ...

    Looking at my iMac's system profiler, the DVD drive is on an ATA bus (which, as I remember it, is slower than S-ATA). What kind of transfer rates do you think one could realistically expect with a hard drive on this ATA bus? Also, would I have to be careful about new hard drive compatibility, or are S-ATA and S-ATA II backwards compatible with ATA?

    thanks a lot for your help,
    Paul
