Sounds good. May I ask some questions?
Have you ever built a computer before? Do you have some experience in building anything electronic?
Do you have one or good good buddies that share lour interests?
If something goes wrong, do you have enough cash to buy a replacement part?
Here is an gut feeling I have. It does not hurt to buy a motherboard with a builtin-in video chip. You can first bring up the system with the bonbon video and check everything out. My personal mishaps have been with video carts. So I am afraid of putting in the GPU until I know everything is working fine.
Now about the motherboard. I am not qualified to comment on that model, I have had no experience with any MSI boards.
