    When you press the eject button.. does it open both superdrives? Or is there a way to control individual ones to open?

    I believe it's Eject to do the one, and then Opt+Eject to do the other.

    That is correct. I would also recommend adding a SATA optical instead of another PATA drive It will allow you to use both drives at once without any bandwidth issues.

    For instance, I had problems burning two CD's at once.

    Are the cables for the 2nd optical drives SATA?

    No, but there are free SATA ports on the logic board that you can use if you have a SATA cable.

    If you use the SATA port on the logic board.. wouldnt that steal part of the bandwidth from your 4 hdd?

    No, there are two unused SATA ports behind the fan assembly.

    SATA is one device per channel. there is no sharing/stealing bandwidth as each channel is on its own and has full bandwidth.

    with IDE (original), there is one master and one slave on a single channel. IDE also has the limitation of doing a single write/read per device on a single channel at a time, so burning 2 at once would be tough... burn 1, read, burn 2, read, burn 1, read, burn 2, etc.

    I have two IDE opticals in my Mac Pro and I've had no trouble doing two things at once (one buring, one ripping, two buring, etc). Buffer underrun protection is your friend.
