I already own this build since summer 2011, but after two years, in summer 2013 I wanted to install Mac OS X on my build.
The reason for this was to develop iPhone applications. Since I didn't want to spend so much money on Apple hardware.
I also own a MacBook from early 2008, but Mountain Lion is not supported on that. Hence also the reason to go for Hackintosh builds.
I previously owned an ASUS P8H61-M LE revision 3.0 motherboard, but in the process of flashing my BIOS, I bricked it. So now I own the recommended Gigabyte GA-Z77-DS3H for a Hackintosh build. Note that I already have a separate Western Digital 500 GB Sata2 @ 7200 RPM Hard Drive with Windows 7 running on it. So with my build I can boot into Windows 7 and Mac OS X 10.8.x (Mountain Lion).
The build and installation is a success.


Step 1 (I followed these steps on an existing machine with Mac OS X 10.6.8 or newer)
-Purchase Mountain Lion from the Mac App Store
-Download UniBeast from tonymacx86
-Insert the USB Flash Drive
-Run Disk Utility
-Partition the Flash Drive to Mac OS X Journaled with Options set to MBR
-Run UniBeast
-Follow the steps and create the bootable USB Mountain Lion installation
Note: This took about 10~20 minutes
-Backup System/Library/Extensions/ATI6000Controller.kext (S/L/E/ATI6000Controller.kext) in the UniBeast Drive (tip: it's a hidden folder)
-Remove ATI6000Controller.kext from S/L/E

Step 2 (I followed these steps with the GPU plugged in and using the GPU's HDMI output on a 1080p monitor)
-Insert the USB Flash Drive in the PC
-Boot into BIOS
-Load Optimized Settings
-Set Sata Mode to AHCI Note: If you have an existing Windows Drive, make sure to Enable AHCI in Windows BEFORE you set Sata Mode to AHCI in the BIOS!
-Save and Exit
-Boot from the USB Drive
-In UniBeast enter GraphicsEnabler=No -x
-UniBeast will load the Mountain Lion installation screen
-Choose the English language
-Run Disk Utility and create a partition on the Hard Drive (Mac OS X Journaled, with options set to GUID)
-Install Mountain Lion on the Hard Drive
Note: If the screen gets white and the mouse freezes during installation, press the spacebar to resume
-Reboot after installation

Step 3
-Boot from the USB Drive
-Select the Mountain Lion installation in UniBeast and enter GraphicsEnabler=No -x
-Run Mountain Lion Setup
-The Ethernet Controller works, so open Safari and go to tonymacx86
-Download MultiBeast and KextBeast
-Run MultiBeast
-See screenshot below for the options selected in MultiBeast (5.4.1)

View attachment MB2.tiff
-Close MultiBeast after installation
-Put the ATI6000Controller.kext on the Desktop
-Run KextBeast

Step 4
-Boot into the USB Drive
-Select UniBeast and enter with GraphicsEnabler=No -x
-Run Disk Utility
-Unmount the Mountain Lion Hard Drive
-Click on Info with the unmounted Hard Drive selected
-Note the disk (e.g. disk1s2)
-Close Disk Utility
-Run Terminal
-Enter dd if=/Volume/XXX/usr/standalone/i386/boot1h of=/dev/YYY
!NOTE! replace XXX with the name of the USB Flash Drive (e.g. my USB Flash Drive's name was Kingston) and replace YYY with the disk name (e.g. disk1s2)
-Exit Terminal
-Exit the Mountain Lion Installer and reboot

Step 5
-Now boot into the HardDrive where Mountain Lion is installed on (don't choose the one with UEFI before it, but the one with P and a number e.g. P3)
-At this point GraphicsEnabler is set to Yes by MultiBeast and you should be able to boot Mountain Lion from Chimera
NOTE: If after the verbose mode a white screen appears and you can move the mouse, push the power button on your PC. Then press any key and the login screen should appear.

Step 6
-Since Intel i5 2400 has HD2000 and Mac OS X doesn't support this, you will occasionally get an error about AppleIntelFramebufferCapri.kext.
-To get rid of this error, follow this guide from Mieze:
-There is no initial audio from the HDMI output of the GPU. I fixed this using this guide from Toledo:
