Nvidea Jetson AGX Xavier is an ultimate validator for Cyber network at this point
https://developer.nvidia.com/embedded/jetson-agx-xavier-developer-kitPriced at around ~$800 (depending on location) gives 512 cores for Rank / Reputation / Luminosity computation and 32 GB of convergent memory which gives upper bound around 500M cyberlinks.
If we asume that every Hero have to operate at least 2 of this (one validating and one sentry) this gives us rougth estimation of (146 * 2 * 800) = ~250k of investment into infrustructure of NMR (network for minimum resistance) or ~180 ETH at current prices. This is an insignificant amount of investment into the proof that Big7 (MSFT, APPL, FB, GOOG, AMZN, TCEHU, BABA) resistance is possible indeed.
