    looking good and very interesting as I know this will be a future project for me with a Mac Pro 1,1 we have here. Already got my G5 and now working on the Quicksilver G4 so the Mac Pro would make a nice group :D

    Good luck with it :thumbup:

    I'm trying to wire up my SATA to USB front panel wiring using Aquaman's wiring diagram.

    So I split open a SATA connector and found out all the insulated wires were white... plus (4) bare ground wire (without insulation).

    So I had to do my own mapping. Using official SATA pinout diagrams and USB headers pinout diagrams, I noticed some discrepancy in Aquaman's wiring diagram*, and I'm posting my corrections below.

    * In Aquaman's wiring diagram, he had a note saying "you may have to reverse the + and - data connections if one or both ports do not work." -- Now I know why, because on the 2nd USB port in his diagram, the D+ and D- lines were swapped incorrectly.

    Also, in Aquaman's original diagram, the (2) center Ground lines are not connected to anything. That 10th pin is NC (Not Connected, unused) on the motherboard.

    In my revision, they are now connected to GND to their respective USB grounds.

    I think I'm done with all my custom cable needs. Made a SATA to USB cable tonight.

    For the motherboard standoffs, I used 18-8 Stainless Steel, M3.5, 8mm length, 0.6mm pitch - costs $9.12 for a pack of 100pcs
    McMasterCarr - 92000A153

    JB Weld, $5.91
    McMasterCarr - 7605A11

    You can also see 4-port USB bracket, and Motherboard power supply extension cables in the photo above.

    Hi powerpcg5,

    I was wondering where you got the board that you are using to plug in all of your hard drives. Thanks in advance.
