If your vanity fits tight against 2 or more walls; once you cut the PEX below the angle stops, you're gonna have a heck of a time putting the vanity back in place when you're finished. Lining up the PEX with the existing holes in the cabinet will prove nearly impossible.
While you have the vanity out, I would suggest either enlarging the holes for the water lines or use a saw to cut out the bottom of the cabinet behind the "base board skirting" (for lack of a better term) so your hands will fit underneath to help guide the water lines back in place.
