Step 5: Mount on wall
Mounting the cases to the wall involved removing the lids, drilling through the wood panel on the back, and using sheetrock anchors.
Once attached to the wall, I reinstalled the lids and replaced the screws that attach the lid to the wood panel in the back.
All that's left to do is for my wife to decide what she wants to put on these new "shelves." Fortunately, I'm not allowed to do the decorating......!
