I've had a dusty S9 sit there for half a day "on" but not submitting shares because a cheap router decided it hated that MAC address... Ha, nothing feels worse than realizing you were burning 1.6 kW into a void.
Since your power rate is the same in all those spots, the real constraint is going to be wiring and cooling. I'd have whoever is doing the work check the circuits as if you're installing a small oven that never turns off: dedicated breakers, high gauge wires and enough airflow that you're not dumping all that heat into a tiny room and cooking the gear. S9s will happily run themselves into early graves if you let temps creep.
On the SoloCK side, you're in the fun-but-brutal zone, it seems. Enough hashrate to see your name on the user-diff board, nowhere near enough to have reasonable odds in human time.
soon to be double the Hashrate!
