Power Supply: EVGA 700W BR
Graphics Card: MSI RX 580 8GB
Hard Disk: TeamGroup 1TB SSD - SPCC Solid State Disk (reused from an old build, already running Big Sur)
Chipset: Intel Series 500 - SATA AHCI Controller
Wi-Fi: Intel Wi-Fi 6 AX201 160 MHz
Ethernet: Realtek RTL8125 Gaming 2.6 GbE Family Controller
Audio: Realtek ALC1220-VB - Intel HD Audio Controller
Audio: Intel Kaby Lake HDMI - Intel HD Audio Controller

Followed the Dortania Guide to build the OpenCore (latest version) EFI in a Flash Drive.
Replaced the contents of the old EFI in the SSD drive with the new one.
1. On Board Audio (ALC1220-VB)
2. Intel Wi-Fi
3. Intel Bluetooth
5. Graphics (including HDMI Audio)
6. Graphics Hardware Acceleration
What doesn't work
1. AirDrop, likely due to the Bluetooth/Wi-Fi card being Intel. The developer of the OpenIntelWireless kext says that, as of now, Continuity is very limited.
The card was recognized properly and the kext was loaded. However, my router/switch was not capable of negotiating the 2.5 Gbps speeds and it was causing it to not connect and tell me that the cable was not plugged.
This was solved by manually specifying the connection to be 1000 BaseT.
2. Intel UHD 630 Graphics Card
The Intel Graphics card is configured to run as an empty framebuffer. It cannot drive a display. It is used exclusively for processing. The Monitors are being driven by the MSI RX 580.
3. BIOS Settings
I basically did a factory defaults and then enabled:
1. Gaming Profile
2. SATA drives HOT Pluggable
3. Chose OS as Windows 10 with UEFI (WHQLI or something like that)
4. Enable Internal Graphics card
5. Start with PCI Graphics card
Reference: OhChang's Build
I want to thank OhChang for sharing his EFI. It helped solved the USB ports not being responsive by adding 2 SSDT files.
Remember to generate your own SMBIOS and to change the following values in the OpenCore config.plist.
I chose iMac20,1 as it has the same processor: i7-10700K. iMac20,2 have the i9 version.
