I agree with the recommendation from GOA, I run almost the same config. Minor difference in graphics card manufacturer. I use water cooling but no opinion either way on which is best, I have always used Noctua fans before and they are superb.
I run DCS in VR with very satisfactory results. If you do purchase the Taichi then don't be in too big a rush to upgrade the BIOS as one of them, I will need to check which version, reduces the SSD performance.
GOA, if you are reading this i wouldn't mind seeing your overclock settings in your BIOS to get the stable 5.0 Ghz.
