I didn’t want to have to paint or cut the metal angles - plus I wanted 4 basket tall so I used pre-drilled melamine for the sides making the unit 48” tall. Then cut top and bottom same as plans and bought 5mm L shelf pegs and had shelves cut 24 1/4”. Used white wainscot panel for back. Very easy - especially since I had big box store make all my cuts! Just have to make sure you have peg holes lined up at bottom or you won’t be level.
