Thank you for the suggestions, I will look into those boards, though I know ASUS isn't really in the best light right now I do prefer them as my brand though there isn't really a great selection from them unless the big jump to the B650E-E for 350$, but that seems a bit wasteful.
One thing I forgot to include in my original post is that I need 3 nvme slots as I will get a high capacity nvme in the future as my 2 current ones are only 1 TB each, my bad.
I do personally thing the 850 watt psu wouldn't be enough, though quite a bit cheaper I think spending the bit extra just to be 100% safe is the way to go for me.
and lastly, that Corsair case looks pretty good I'm going to look into it, I originally picked the Hyte Y60 simply because I use the O11 dynamic currently and they are pretty similar.
