I am using debug mode and prebuilds just to get proof of concept, going to reconfigure and make custom files next. I need to tweak usb settings, dial in gpu, and upgrade to newer os.

everything is pretty much working out of the box. i haven't tested bluetooth, but headphones audio, screen display, and usb is working.

This is a really fun build process, great community, and just enough hacking pain and puzzles to make for an awesome project!

Took about 3 days of tinkering.

Good luck out there!

Ran into issues with- - usb stick not being in usb2.x port - slowly but surely collected feedback with log files and found direct documentation OC fixes for common problems, or no problems finding in the community. (Look for the Err at the end of the log and then google it with your motherboard) - I was lucky enough to have a decent architecture for this build (Z370), I have been wanting to do this project and took advantage of cheap Radeon card prices. - When I do a rebuild i will document all the quirks i had, but almost every issue was either bios, or a config.plist edit. - Make sure you update your BIOS on mobo, and use a usb stick to download the newest (v. 3005 on may 25 2023). Do not trust the built in bios updater, mine told me i was up to date with an old bios, and i lost a day of troubleshooting thinking i have the newest version.

Truly pumped about this, thanks again yall
