@scottpilgrim Yeah the Gigabyte Aorus Master sounds like a good option for 150 new.
The Realtek ALC 1220-VB audio drivers shouldn’t be too hard to find.
I did find this modded driver that I have not verified it in any way (so make sure to scan for virus etc) → Realtek_HDA_6.0.1.8272_DTS_DDL_experimental.zip
The Intel i225 driver mod for Windows 7 is mentioned in this thread → Installing i225-v ethernet drivers (W10 drivers) on windows 7?
The Intel Wi-Fi 6 AX201 driver for WIndows 7 on Softpedia → Intel PROSet/Wireless Driver (IT Administrators) 21.40.5 for Windows 7 64-bit
I am not 100% sure if it will have the exact Device ID, but you could potentially modify the .inf file if it is not included.
For the USB 3.0 drivers it may be a bit trickier, you may want to look at the Simplix project (warning, Russian language) which may be easier to follow on MDL fourms.
I believe it should be possible to get everything working but it may be a bit time consuming.
I would suggest to make an image of your OS drive with Macrium Reflect (or similar) one you have all drivers installed and devices working.
