Love how easy it goes up. It is confusing about marking where the panels go as there are no measurements. We just located the studs and then measured the 84 and back down 8.5 to hang the metal piece that the panels hang onto. It all worked out. We bought this closet system and one 12 drawer and two 8 drawers to add to the bottom of the tower. The drawer instructions tell you how to mount the drawer slides and the back of the closet system instructions tell you what holes to mount the glide counterpart. They say to put the drawer glides on the vertical panel at holes 3, 9, 15. We put them at holes 3, 12 15. We did bring the stationary shelf in hole 23, down to hole 22. You still have two adjustable shelves above the drawers. It just takes time but the drawers were easy to put together and came with templates for the glides, screws and even glue packets for each drawer! EasyPeasy. I bought white. Its going to hold up great.
