Msi z390 Edge Ac ATX

Hi everyone! New here!

I just got this setup and I was wondering if I would be able to install a hackingtosh on it.

All parts are brand new, besides the RTX 2070 I got a couple months ago. ( I am aware these aren't compatible GPUs ). What gpu would you guys recommend and why?

SETUP LIST: CPU: i7 9700k MOBO: MSI z390 Edge AC ATX MEM: Teamgroup 16GB 3600Mhz DISK: GALAX Gamer 240GB PSU: CORSAIR RM850X

*Saving for a NVMe drive for Windows partition and custom watercooling when I can afford.

Suggestions are always welcome. Big thanks in advance!
