I like the possibility of having tons of high-end GPUs being sold for bargain basement prices on eBay.
One of my never-started projects is to build a big GPU=based cluster shaped like a Cray-2. The original machine had, IIRC, 11 lobes and, therefore, having 11 GPU cards feels right (or 10 and use one lobe for the motherboard controlling everything. A Xeon Phi (if we are going crazy with GPUs, we should go crazy with the motherboard as well) has 36 PICe lanes, so I assume it'd be a fine choice. All this would be immersed in 3M's Novec 649 to keep the bubbly looks.
He wants a gpu compute cluster, not a notebook mining machine. They would be on the market because bitcoin's price is so tightly linked to many others including ethereum.
