I've finished creating power and space ratings for Eldar, Dark Eldar, and Tau starship components.  Such components are generally amazingly effective and quite compact, but draw a bit too much power to fit well on ships with plasma drives.  If you can get the drive from a xeno ship and mount it in an Imperial ship, though...<br/><br/>If you can get an Eldar or Dark Eldar drive, you also can use their Supreme Maneuverability rule.
