    New York, Baby!
    I've been given a PowerMac G4, which I guess was OK, but seemed very slow.

    So after being paid and being able to get the case home, I was able to think properly about what I could do with it.

    The best option, after seeing Nomar383's own work, was to remove the guts of the G4 and get intel parts into the case. This is on a tight budget, so I'm using last generation equipment to keep the costs down.

    Part List
    -Intel E5400 2.7GHz Dual Core processor
    -2GB Mushkin DDR3 RAM
    -MSI G41M-P25 Motherboard
    -nVidia GT220 512MB RAM Graphics Card
    -450w PSU
    -1TB 7200rpm disk that is currently just used for Aperture

    -Philips Screwdriver
    -Small Allen Key
    -Dremel (or similar)
    -Cutting discs that can get through hard metal
    -Soldering iron
    -Blunt nosed pliers

    Case prep
    After removing the PowerPC components you'll probably go rushing for your motherboard, eager to see if it will fit. Let me stop you - it won't! Not only are the standoffs in the wrong place, the backplane is for the old Powermac system board, you need to start your path of destruction.

    With the blunt nosed pliers, you want to grip the standoff from directly above and rock forward and back until it just pops off.
    The door will look something like this:
    Here are the offending standoffs
    These are what hold the standoffs in on the door, they should just fall out.

    My next stage is to get the back acrylic panel ready so I can plug power into my PowerHac, so with the new Dremel (well, it's a Draper) I got to work with a spinning diamond tipped thingy...

    A blurry picture after dremelling:

    With the PSU in place:

    I will finish it off by sanding away the built up cut plastic when finished.

    This is the piece which wasn't required:

    With the PSU ready, the next step is to cut a large chunk of the backplane out. You need to keep the expansion slots, so drilling the rivets out would be an arduous and possibly counter productive thing to do. I set with my Dremel and at first a diamond spike which worked a treat on plastic, but only goes about a mm on metal. I then fitted a cutting disc, I managed to get halfway along here and the disc had gone to about a quarter of it's original size:

    I then took another disc, it split and got caught between holes, but the next one, I eased in and it got past the end of the vent holes towards the left of the picture above and then i put too much pressure on it and it shattered too.

    I've stopped for tonight as I have some more discs on order, which should be more hard wearing for this metal.

    More to come soon....
