This is great. You could have a maintenance statistic called COMPLEXITY which models this. Rated 1-10, with regular rolls using Engineering/Repair/Electronics/Robotics/Cybernetics to succeed in order to maintain it in proper working condition.
1 - Piston armatures (think Chinese mooks in DXHR). Below human standard. Reduces charisma, social interactions, sensory interactions involving touch, fine motor control is poor.
4 - human-level performance prosthetics, micromotor based. Equivalent to human standard, only minor social penalties in dealign with people who are prejudiced, moderate monthly maintenance costs at local clinic plus weekly medicine.
7 - extraordinary, high-precision, micro-machine augmentations, superior to human standard, requiring weekly maintenance at a hospital or cyber-clinic specialist, plus daily medical drugs/fuel/fluids to maintain optimal performance. Degrades on daily basis. Social penalties as above, bonuses based type as normal cyberware.
9 - superhuman, advanced partial or full-borg reconstruction requiring high-end facilities found only in a few major world cities, daily medical/fluid/part maintenance, intensive repair operations, available only through large governments and corporations, costs so high as to basically mortgage your whole body/life to the maintainer.
