    • The Power Mac G4 MDD: the last, and the fastest G4-based Mac. This computer boasted up to a Dual 1.42GHz PowerPC G4 CPU (though I have a single 1.25GHz).

    • Two USB 1.1 Ports

    • Assorted Audio

    • Video (ADC & DVI)

    • Networking (RJ-45 Ethernet/56k Modem)

    • Some later model MDD's (such as the dual 1.42GHz) Have a FireWire 800 Port Here:

    • The MDD uses a maximum of 2GB PC2700 DDR RAM (512MB X4) and has 4 slots.

    • Now, lift the heatsink up off the computer, it is pretty heavy, because it's a giant block of aluminum.

    • Be careful when holding it, the edges can be sharp, making it likely to get cut if you hold it wrong!

    • As you may be able to tell, i have applied a replacement coat of Arctic Silver 5 to keep my MDD cooler than the stock paste, it really does a great job too!

    • The incredibly large heatsink, this thing is 5 Lbs of solid aluminum. Just like every other part in this, and many other Macs, the heatsink is made by: ...you guessed it, Foxconn.

    • Before reinstalling, ensure that you clean the old thermal paste off of the heatsink with alcohol.
