The granddaddy of mainframes, System/360, was never in 19" racks. IBM first introduced the use of 19" racks in their midrange lines. What we currently call IBM z didn't adopt standard racks until the 21st century.

I find 19" racks a bit too thin and tall. Definitely their 24" ones were the right proportions.
