The PS2 release price was $299 USD. Consoles used to be cheap.
But these days, consoles aren't sold below cost, and gigabit network isn't fast enough to make cluster computing make sense
A 64 bit MIPS processor that can run linux + networking for 299$.
I know is not exactly the same but how much was a SGI workstation 20k? 40k? 80k?
If the PS5 had a Nvidia A100 the comparasion would make sense and people would be buying them to create clusters, like they did with the PS2 and 3.
