In Sid Meier's Alpha Centauri (SMAC), the Cyborg Factory is a Secret Project. It may be built at a cost of 360 minerals, on discovery of Mind/Machine Interface (C6). It provides a Bioenhancement Center at each of your bases: +2 Morale for non-native units subsequently built, or +1 Lifecycle for native units. Since Bioenhancement Centers cost 90 minerals, the Cyborg Factory is a bargain at the price of only 4 Bioenhancement Centers.

Secret Project animation narrative:
   "A handsome young Cyborg named Ace
   Wooed women at every base,
      But once ladies glanced at
      His special enhancement
   They vanished with nary a trace."
