Did you check my mega post regarding the L12s and a Gigabyte x570? (Same socket’s height).
I am pretty sure that also the other MB will have issue with the side struts!
BTW, if you mount the L12s in the NOT suggested way from Noctua, so with the end of the pipes facing down, IT FITS WITH the side strut, I’ve personally checked this.
The “Ghost Edition” is basically the L12 with the old B9 fan as well, BUT without the 120mm fan included ? The L12 fits quite well in the case, but I trust you
