    The AirPort card is located next to the graphics card. If your computer has a FireWire 800 port between the FireWire 400 Ports and the Ethernet Ports then your computer uses an AirPort Extreme 802.11g Card (See Related Parts). If your computer has no firewire 800 port, then your computer uses an 802.11b AirPort PCMCIA Card (Also See Related Parts). Removal of both cards is pretty much the same. First disconnect the antenna from the card, it may be helpful to use a spudger or flathead screwdriver.

    The power supply has a 24-pin connector with non-standard voltages, so dropping in a 24-pin ATX power supply without modification isn't a great idea. The power supply connector has a 25V lead to drive Apple ADC displays, so though it is possible to modify an ATX power supply, it won't be able to drive ADC displays, just VGA, or DVI, though the computer will work fine (I've actually tried this).

Any idea if that heatsink can be used for a dual 1.42GHz board or must I get the copper heatsink?

Hi, thanks for the good job you do, I'm restoring my old G4 MDD and I wanted to know if it's possible for you to be able to install a 256gb ssd on this machine using a common sata - ide adapter. Does Leopard really run too? And how is the performance?
