Comments:
Built installation USB with Unibeast 6.2 and App Store El Capitan download (on Real mac running 10.11.5). Followed guide. IMPORTANT - partition USB correctly

Summary:
Initial install stalled on graphics load (after bluetooth message). Disabled Intel graphics injection in clover and installed OSX to SSD drive (added to pc).
Reboot (still required disabling Intel injection) - get welcome screen.
Run Multibeast for Audio(intel) and Network(intel 1217LM)
Fix graphics - see post "Intel HD 4400 Desktop Graphics Fix - Full Support for Alternate CPUs in OS X"
(Installed kexts with KextBeast)
IMPORTANT: After disabling Intel graphics (before installing fakePCID.kext and fakePCID_Intel_HD_Graphics.kext) I had to enable Intel injection again - see this snippet of config.plist

    <key>Graphics</key>
    <dict>
        <key>Inject</key>
        <dict>
            <key>ATI</key>
            <false/>
            <key>Intel</key>
            <true/>
            <key>NVidia</key>
            <false/>
        </dict>
    </dict>

(used EFI Mounter to access EFI partition)

Works:
Audio
Network
Display
DVD Burner
USB

Summary:
Most of the hassle was getting the USB built, MBR partitioning seemed problematic. The Intel graphics issue for install can be fixed in the boot options. Recommend getting your lspci before you add drivers! Great info source here at tonymacx86, well done people.

The Intel video issue seems to depend on whether you use VGA of HDMI. My Initial build was with VGA (which still requires disabling intel to work) whereas using the HDMI now works with injection (where VGA does not). I'm guessing there is some basic frame buffer at work with the vga port.

where did you get your audio driver?

I ended up using a usb dongle.
