Just a small question, why the hell are you going for a halo tier board? You do realsie that you can get a board with all the features you need for less than half the price?
Honestly all told you seem to be going for the most expesnive option regardless of the performance apart from getting a mech harddrive with a budget nortyh of 4 grand for some reason, for example the RAM kit you have will perform worse than a 3600MHZ kit that costs 1/4 of the price if you went with ryzen. Would you like a sensible build putting together if you just list what you want for example do you want RGB and what colour wouldf you like?
