I can see the cost being a deterrent; 4000 in minerals is pretty hefty, but the size shouldn't be. A master computer III is smaller than the bridge, crew and life support components it replaces and MC II is identical in size, its only MC I that is bigger. I make use of them in some smaller ship designs in the mid-later game when I really need that extra 10 Ktons more than the 4000 minerals.
