So with 8 customers per box (AMD EPYC™ 9645 CPU has 96 cores) if they have single-cpu boxes, that would need 256 GiB RAM.

CPU launch price 11000 USD. RAM will likely be another 10000 USD

20000 / 8 customers / 40 USD/mo = 62 months just to recoup CPU and RAM let alone other components.

Weird, whenever I napkin math offers of any HW for renting, I get that I could buy it myself in 1-2 years of rent. Sometimes faster.

Do they not intend to recoup the costs of HW? :)

Oversubscribe your hardware and you can do better. Most of your customers are idle most of the time.

the most important question is the power, such a setup will blow through easily 500W of power. Granted, a datacenter may not pay 33 ct/kWh but even then, 1/3rd of the monthly income will just go towards naked electricity, not including cooling.

Electricity costs are ridiculous.
