well, unlike some games such as CoH/CoV, WoW which only have a limited set of choices for customization (creating the character in those games cases), the shipbuilder has a potential for a near infinite combinations because there are so many choices and many hardpoints, and each piece actually adds hardpoints, so it'll look like some randomized mess with possibly hundreds of thousands of pieces and you don't even know what's connected to what if you wanted to remove some pieces. in some games, the randomization feature is nice, but because of the near infinite number of combinations of jewlery parts in the shipbuilder, it would eat up system resources and probably cause a CTD.
