Naturally; it should be hoarded in my glorified homelab, where I can more readily listen to the sweet purr of fans.

I'm assuming his friend's finance company is planning to make use of the cloud compute they find in some finance workload.

I don't think they're buying GPUs outright to store in a warehouse.

Any sort of hardware produced in the last 5 years has at least doubled in price. Some, like RAM are 3-5x more expensive.

So whoever hoarded it in warehouses could sell it now immediately for at least 100% profit.

They seem like geniuses to me now, worst case they make 100% profit on the investment.

It's only RAM, mass storage and GPUs. Desktop CPUs, mainboards, PSUs, and cases have become cheaper because PC building demand has declined. Peripheral prices have remained largely unchanged.

But a large reason for the price increase has been because companies have been hoarding them in warehouses as they wait for DC buildout. If you sell then you remove that pressure and prices decrease.
