I recall a while ago seeing items that make your HA look like they have cyborg parts. I think they looked like mechanical parts were under the skin. If someone could help me out that would be great.

Some of the body mods at Rachelle's might do the trick. Otherwise... items with the word 'gear' or 'cog' in them e.g. Some of the items in the shiny blue orb costume trunk or Intergalactic Warfare Costume Trunk (you can buy them off shop search, not just there). Also , but that's a CW (an awesome one though).
