I think the biggest issue is getting the graphics working/recognized properly by osx. I tried every single ig-platform-id in clover and I could not get it to work. even the last one I posted is not working anymore it hangs on boot. The only way to get it to boot is to use -x in the boot arguments. I am pretty sure I did not have to use -x to do the install.
I could not get sound working yet. I tried some AppleHDA.kext for ALC269 but I could not get it working. I am not sure if these kext get loaded after the video. I may try voodoohda next.
The pcie card for wifi that comes with the brix is not supported so you need to get something like this

and install toledaARPT.kext to get wifi and bluetooh working (

Ethernet seems to be recognized using rehabman kext (
https://github.com/RehabMan/OS-X-Realtek-Network). It shows in the system properties but I have not tested since I am using wifi.
I have also used rehabman version of fakesmc.kext (
https://bitbucket.org/RehabMan/os-x-fakesmc-kozlek/downloads) to pass the right smc version. I had to edit fakesmc as following:
open down REV, RVBF and RVUF. By default, FakeSMC is using SMC version 1.30f3 which is displayed in Data field as 01300F00 0003. Replace with 02140F00 0019 2.14f19 that is the version for iMac14,1
I also added a SMBIOS section in config.plist with information for iMac14,1 that I found on the web but I am not sure if that is the right info.
The following guide to install clover is the best I found for this system:

Attached is all the kext and config.plist in the right folder structure that I am using for clover. you just need to copy and paste on your clover usb install.
