Need suggestions for new build

In the coming months I would like to build a new Hackintosh.

I have one now, but it's getting long in the tooth.

• I want to have a mother board that will accommodate two M2 cards so I can dual boot (OSX/Windows)
• A board that can accommodate my VEGA 64 card
• One that has Thunderbolt 3
• I have a Fenvi T919 in my current rig that works great w/ OSX that I'd like to drop in the new rig. (So I'll need a slot for that!)

The smaller the footprint the better :)

​

Sooo...with that in mind, can anyone recommend a board that will meet/exceed these requirements?

​

Thanks in advance.
