A tiny single bear metal server, at that; most server hardware I use has 48 cores!

Running it at Raspberry Pi would cost you 8k.

There is like nothing where that would be cheap. Even if you looked for something that has very high IPC and clock rate.... the CPU with that will have at least 4 cores if not more.
