Everything you could possibly want to know about doing it right is in that great thread:
The VFD “just” needs to be somewhere where it will having a little breathing room, it does not have to be very close (you won’t interact with it much once installed anyway)
My setup does not have drag chains, so I just hang the spindle cable and cooling tubes from the ceiling of my enclosure. For a Shapeoko3 it works, for an XL or XXL the drag chain approach is much better.
