again, I greatly appreciate all your input guys.

omg phil, thx for those links... you're a life saver.
I will definitely go with the HP pdu and the c20 to c13 cords.
The psus are the apw3++ (got them with the ants from bitmain)

Saturday we'll have the electrician come over and see what we can do.
This will be set up in a friends basement I guess we'll have to wait and see the voltage lottery coming in from the street.

Any tips on how to set these up to be power cycle-able remotely?
Is there a c20 smart plug that could work with these??? not sure how steady/reliable these S9s are... back in the day my S1 would go for months unattended.
I guess I'll have to manually reboot them if nothing else. (which will suck cause my buddy's shop is across town)
