Your setup looks fantastic and should have no issues running StartOS smoothly. The Intel Core Ultra 7 155H, Intel Arc Graphics, 4TB SN850X SSD, and 32GB of DDR5 memory are all top-notch choices.
If price is a concern, the NUC 13 Pro will still run StartOS well. I found one user who reported success with an ASUS NUC in our forum.
