A modular rack includes at least three spaced post units, a plurality of tubular sleeves and a plurality of trays. Each of the post units includes a hollow upper post, a cylindrical connector, and a hollow lower post. Each of the upper and lower posts has an outer surface formed with a plurality of annular peripheral grooves. The connector threadedly interconnects the upper and lower post. The connector further includes a radially protruding flange portion between the upper and lower posts. The flange portion has an outer diameter smaller than that of the upper and lower posts and cooperates with the upper and lower posts to form an annular retaining groove. The tubular sleeves are sleeved on the post units. Each of the tubular sleeves is formed with a radial inward protrusion which extends into a selected one of the peripheral and retaining grooves in the upper and lower posts. Each of the trays has a peripheral portion provided with at least three spaced positioning tubes and has a length which is at least equal to the length of each of the upper and lower posts. Each of the positioning tubes is sleeved tightly on one of the tubular sleeves.
