That's not true at all. Next to power deliver, power removal--aka HVAC--is next in line of recurring costs (after one-time costs of building the facility and the initial server BOM).

For example: https://perspectives.mvdirona.com/2008/11/cost-of-power-in-l...

Unless by "mainframe" you mean specialty compute-server farm for a supercomputer (with massive IO) then perhaps.

IBM z chip is for mainframe and it's too expensive and normally not massively scaled out compared to cloud servers.
