An enclosure for a data storage system comprises at least first and second cast magnesium parts joined by rivets, each of which is made of a suitable material that provides compressive strength superior to that of the cast magnesium. Each rivet is of a height or thickness equal to the sum of the thickness of the parts to be riveted. Each such rivet has flat end surfaces and its body is peripherally concave between its ends. The rivet is embedded in the two parts, and the parts flow radially against the concave body of the rivet. No drilling is required, and the parts are held in carefully defined position while being joined, so that the assembled enclosure satisfies strict dimensional tolerances.
