Dual Boot Windows/MacOS Build

This is my first Hackintosh build, and my first PC build in about 8 years so I'm fairly out of the loop with the community.

I'm looking at building a PC that can double as a home studio work machine in MacOS, and a PC that can do some light gaming in windows. The plan at the moment is to split the hardrives, 1 sata and 1 HDD for each side of the system.

I'd read on another thread that you can load 2 separate GPUs for each system, so I plan to use onboard graphics for the MacOS.

I just wanted some advice on the build, if there is anything in the build that won't work, or any advice to make the system more efficient or "better".
