No issue with anything, will work well :- ).
I would suggest though, to either go for MSI MEG, or Gigabyte Aorus Xtreme. These really are the only two good boards for 2990WX (for any other CPU, the rest is also great). Zenith would be ok board, but not with its price.
Since you are going for U14S, Aorus Xtreme might be the better choice as you won't be overclocking. More phases and better cooling of them are well worth it for 2990WX.
I also personally don't like much 2080 RTX. It has weaker NV-Link bandwidth than 2080ti, so in future, if you would like to add second gpu and connect them for memory pooling (for GPU rendering), the performance will be much worse.
At same time, the price is on level of older 1080ti, which has 11GB Vram, a lot more for viewport&denoising with Optix.
Yes it's more "current" but 2080 doesn't have enough raw performance to use RTX cores for anything (and DLSS is only for select gaming). For workstation use, it's vastly inferior to 1080ti. For gaming it's a tie. For GPU rendering, it's better...but then I would go all the way with overpriced 2080ti.
Your memory as of now, will not run at 3200MHz, but it might theoretically in future as chipset updates will rollout with newer bios. The current stable frequency for 2990WX memory is 2933.
But the above is personal opinion, as you have it right now, it's a good build.
