Abstract: A modular cabinet system is disclosed. Posts are mounted between a top member and a bottom member to form a sturdy frame. The frame is configured to slidably receive side panels to form an exterior. The frame is also configured to receive doors and shelving to form a door cabinet or drawers to form a drawer cabinet. The doors rotate on a hinge rod, which is received in the top and bottom members of the frame. Alternatively, the frame receives a set of drawers. The frame slidably receives drawer brackets in the posts of the frame. The drawer brackets are spaced to provide a desired clearance between drawers. The disclosed cabinets use the same frame and panels whether the cabinet is to receive doors or drawers. The cabinet is also easily assembled such that it can be shipped in a compacted form and assembled by the purchaser or user.
