No drawer slides. Going for simplicity, and since the shelves are 3/4" I don’t see them wearing out. Since I am planning on having 5" and 3" vertical facing boards to help with torque issues, I will probably lay down wooden guides along the sides where these overlap, just to keep the drawer movement square, but nothing fancy.

I may also coat the shelves with a wipe-on varnish to help with longevity and to minimize splinters, but that is about it.
