You're making a box with 90° corners from ¾ Baltic birch plywood.
Use some TiteBond III and just glue the box together. Start with the two long sides and a short side. Use the bottom, but not glued, to keep box square. After the glue sets for an hour, glue the bottom and remaining side. You'll only need two clamps.
If you are really paranoid you can shoot some nails or use the screws. I wouldn't as the glue is stronger than using screws.
