    Would a motherboard from a 12,1 (Quad 2.5) easily fit into an earlier G5 case? Would the psu (wattage permitting) from the earlier G5 work on the 12,1? Meaning, is the pinout of the connector the same?

    I've not done a deep dive on this, just curious.

    As for the motherboard - I guess it could fit in the case (not sure about the mounting points though), but:
    1. The power button module is different
    2. The ports at the back look different
    3. 12,1 has got an additional AirPort/Bluetooth antenna in the back

    Now when it comes to power supply - it's a different pair of shoes. The wattage is one thing - Quad's got a 1000W PSU - but the plug connector is completely different. 7,3 is using somewhat standard ATX-ish connector style while 11,2 is using a series of metal "badges" that have corresponding points on the mobo (and they're screwed together).

    Not worth the hassle, I believe.

    12,1 = iMac G5 iSight
    11,2 = PowerMac G5 PCIe

    Exactly the info I was fishing for, yeah not worth it.

    Thanks.

    There was a Video on Youtube once from EEVblogs Dave, picturing him very impressed by the engineering of said powerbars in a G5 machine.

    They may be the next best thing since sliced bread, but if you want to take out the power supply in "late" G5 you will have to remove everything. gfx card, CPU module(s), power switch, motherboard...
