Would love for all go as a set, but open to just moving pieces on. Book cases are 45 wide and 6’ tall. There are 12 movable shelves. Cabinet below is 29” tall 24” deep and each compartment is 45” wide These are minimally attached to the wall with a single screw in each and then screwed to each other with single screws. I assume the cabinet is attached in a similar fashion is it does have a back panel inside. Bring some help and a truck!
