If it is Zed, Silo rushing can start stun/killing commanders at 2.5k metal invested, probably the fastest option if you are running unassisted by other player projects. The alternative is shuttle rush, but delivery is hard. (charon? thunderbird the build site? dirtbag anti-anti cloak?)
The ulti rush proposed is so expensive that it'd never work as a single player project.
