Does the hardware being all so arranged as it is in this manner to create a supercomputer make any difference to that evaluation?
The storage drives for all of this have been stripped. You can't just run commands on the hardware... you have to figure out how to cluster things with software, buy drives for it all, have it all installed in a datacenter somewhere which is going to cost way more than the purchase price.
The labor costs for the technical people required to do this are way more than half a million a year.
