It would be cool to see some raspi hats you could plug a GPU into, though unsure of how practical or feasible that would be. Todays graphics cards are tomorrows e-waste, perhaps they could get a second life beefing up a diy raspi project like this

Most of the USP, outside of the ecosystem developed around the single platform, is to do with form and power draw. Adding in the GPU/adapter/PSU to leverage cheap CUDA cores probably works out worse power/price/form wise than going for a better SoC or x86 NUC solution.

for crypto-mining you'd convert a single PCIe slot into 4 x1 PCIe slots - or just have a board with 12+ x1 PCIe slots. I'm not sure what magic goes in to PCIe, but i do know that at least one commodity board had "exposed" PCIe interface - the Atomic Pi.

anyhow the GPU would sit on a small PCB that would connect to an even smaller PCB in the PCIe slot on the motherboard, via USB3 cable. My point here is merely that whatever PCIe is, it can be transported to a GPU to do work via USB3 cables.
