Wait what? can you show me some sources to back this up? I assume you are exaggerating but still, what would be the definition of cheap is interesting to know.

I don't think after the fact that ram prices spiked 4-5x that its gonna be cheaper to self host by 100x, Like hetzner's or ovh's cloud offerings are cheap

Plus you have to put a lot of money and then still pay for something like colocation if you are competing with them

Even if you aren't, I think that the models are different. They are models of monthly subscription whereas in hardware, you have to purchase it.

It would be interesting tho to compare hardware-as-a-service or similar as well but I don't know if I see them for individual stuff.
