You will likely have to install some spacers or rails depending on whether the slides are bottom mount or side mount. Just a suggestion for the panels on the cabinet, the ends would look better with the grain being oriented vertically. Can't tell if the ends and back are solid wood or plywood. For the ends and back, plywood would be the best choice, as it's more stable and dos not have an expansion and contraction problem.I'm thinking of going with soft close slides and buying the butcher block top. Planning on painting the cabinet and a finish for the butcher block top.
