I finally upgraded from El Capitan to High Sierra 10.13.3 successfully on this GA-X58A motherboard. After a few roadblocks, that I overcame, everything seems to be working including (sleep, shutdown, audio, network, etc..) USB 3.0 doesn't seem to work, as I haven't tried to fix it with the controller being disabled in bios. I'm ok with that.
I will be linking and combining a few guides so its all in one place.
Here are the steps I took:
1.
Backup your current working machine
Use Carbon Copy or Superduper, I backed up and made sure it was a startup disk so I can migrate all my data later, instead of reinstalling all apps from scratch.
2.
Download High Sierra Installer
Google: High Sierra Patcher Tool for High Sierra or Mojave Patcher Tool for Mojave (dosdude1)
3.
Make sure bios is updated on Motherboard, for v2 its FH version.
Check website for latest bios:

4.
Create 2 USB Boot drives
As explained by cSoul in this post (
https://www.tonymacx86.com/threads/success-10-7-5-lion-10-13-2-high-sierra.240960/)
- Create bootable Unibeast Install Drive (Legacy) following this guide: Click Here
- Create bootable USB from Step 2 above, it shows you how in Step 3 on the website.
Once you have both drives created, copy the EFI created partition from the Unibeast install drive to the EFI partition on the drive created above. So, you only have to use 1 USB drive to boot. *This is what I did, and it worked* Since I'm staying with HFS hard drives this worked for me. I didn't want to upgrade my drive to the new APFS protocol since this system is an older system. The Unibeast USB installer didn't recognize the HFS drives properly.
5.
Format SSD & Install High Sierra
Once booted, format your SSD, follow these steps in Step 4:

If you want to keep your drives in HFS, you must also do step #9, which requires using Terminal and typing (
/Volumes/Image\ Volume/No-Convert)
Complete the MacOs Installation in Step 4 and Post Installation using MultiBeast in Step 5:

*Note: Its going to ask you to create a new Admin UserId when setting up High Sierra for the first time, I created something different than my backed up userID, because after I restore everything using Migration Assistant, I will be deleting this Admin User.

MultiBeast Options
Choose Legacy Boot Mode
Under Drivers
- Audio - ALC889
- Disk - default
- Misc - default[/SIZE]
- Network - RealtexRTL8111 v2.21
- USB - default[/SIZE]
- Bootloaders - Clover Legacy
- System Definitions: iMac 14,2
Click Build - Install to SSD
I used the default DSDT and
DID NOT replace it, I tried to replace it with one downloaded from database and lost audio.
If you have an NVIDIA card - download the
Alternate Graphic Drivers for it
eSATA Drive? - follow this guide:

7.
Migration Assistant
If you backed up your system, (I hope you did or get ready to spend hours re-installing) now you can use Migration Assistant to restore all your apps and data. Plug in your backed up startup disk and launch Migration Assistant. When checking the boxes on what to restore, UNCHECK "Other files and folders", or your system won't boot.
Once done, enjoy your new High Sierra system with all your data.
Hope this helps someone out. As mine is running good so far on this old rig.
