You were right, I managed to update OSX to 10.6.7, I tried the 10.6.8 update which failed... I have to start all over again, yeay !!!
Yeah for some reason, I know others know lol, 10.6.8 changed a lot and they removed support for some items so I would hunt down what stuff on your mobo is still supported or not supported.
I wish I knew off the top of my head :/

Well I've reinstalled 10.6.7, and it works. However... I tried to make OSX recognize my HD6870 with this http://www.groths.org/?p=431 and now I get no graphics at all...
Multibeast with Chimera and the ATI FakeSMC plugins a no go?

Changed Drivers & Bootloaders -> Kexts & Enablers -> Miscellaneous -> FakeSMC Plugins to a menu choice.
Added to FakeSMC Plugins -> Motherboard Plugins which only installs the motherboard plugins.
Added to FakeSMC Plugins -> AMD RADEON Plugin which only installs the AMD RADEON GPU plugin.

Hi guys,
here's a little step by step of my G4/G3 mod.
There were a lot of drilling and cutting involved so a dremel-like drill is THE tool to possess !
As you can see in the previous posts, I was unsure whether a full ATX motherboard would fit or not: it does ! Here's what I did:

First you've got to clear the case in order to put the new MB

Obviously drilled holes to secure the G4 MB with screws are not at the right place and new ones must be drilled. Old support tubes should also be removed as seen on the previous picture (their base is well welded and you have to cut them as close as possible to the metal case).
My goal was to place the new MB in such a position that current slots for extension PCI cards could be used as is.

So first you've got to build new "tubes" to support the motherboard:
You must be really precise while drilling new holes and be sure about the MB's place on the case. Then a simple and efficient way to fix the MB is to place small bolts and secure the MB on them:

However in order to do so, you've got to place the MB as close as possible to the case otherwise it will prevent you from closing it:

Because the MB is square and the side case corners are cut, you must also cut one corner of the rear case (and sandpaper it, a lot...)

After doing that, I discovered that the plastic insulation under the MB was also used to open and close the case itself. The new support bolts blocked it and prevented closing the case.

So don't forget to cut a racetrack shaped hole around each bolt !

Once you've finished that, you may think that you're done, you're not !
The motherboard's power supply wires are also preventing you from closing the case as they are blocked by the optical drive... :mrgreen:

Whole lotta drillin' !!!

Still I thought that it was the end, I was wrong, again !
There are two things I didn't notice before everything was plugged in :
1) I can only put one RAM module else you've got to remove the internal optical drive (I chose to keep the internal OD which is a MUST for installing the OS... and re-installing it many times ...)
2) The "very convenient" power button on the MB was blocked by the OD case when closing the case... :banghead:
So I had to cut half of the internal OD case !


DSC00300 par duke.polymtl, sur Flickr

That was not enough to get rid of this issue.
I also had to lower the MB a bit by removing one support nut on the support bolt closest to the power button. However you must be careful because the screws securing the plastic open/close system get very close to the MB, and only one nut should be removed. The MB is slightly twisted but works fine, and now you can close the case.

That's it, you're done for the most part !
I was not yet able to figure out how the original Apple On/Off - Led - Reset card works and connect it to the relevant pins on the MB. As a result the only way to start is the Power button on the MB itself... If someone has an idea ;)

I have to say that it was really fun to undertake this case mod, I cannot say the same about OSX's installation... I currently have no sound and no way to boot without iBoot, any help would also be greatly appreciated !!!
If you've got any question (I may have forgotten to mention intermediate steps) don't hesitate !

Hi guys,
it's been a long time since I last checked this topic, I just wanted to update things: the hackintosh is working great !!! I got rid of the O.D. in order to put 8Gb of ram, however my GPU isn't recognized as a HD8670 but since I have little need of GPU power, I didn't do anything about that.

Edit: the original power button is working too !

I am in the same situation, i need to cut the lower corner to fit the motherboard. But the problem is the the plastic lower handle, this touching the motherboard! How you solved?

hey I have the XFX 5870 Black Edition to fix the card being recognised as radeon 5000 series I changed graphics enabler to yes this also fixed the problem with halved video performance after sleep! hope this helps :)

ah sorry i see what you did... i believe that the 6870 is having problems with more recent versions of osx however i may be mistaken
