The sideboard case bottom is frame and panel construction. Or at least it is now. Originally it was going to be just an open rail/stile frame with no panels, but a bit of thought this morning convinced me to add panels. Time for more mortises, slip tenons and panels. Here are the drawer runners, I'm pre-gluing the slip tenons before assembly. Making furniture (and lots of other things) is a series of decisions. Hopefully you make the right ones. Consistently.
