What is this board with ten Virtex FPGAs on it?

I saw this on eBay while looking for FPGA things. This board has ten Virtex-6 FPGAs on it. Only one side is visible in the pictures, but I see no evidence of any off-chip RAM or any other high-speed interfaces. This is extremely curious to me - what on earth needs so many large FPGAs but has no high speed interfaces?

My best guess is that it's maybe some kind of crypto miner, but I've never heard of a crypto miner using top-end FPGA families which are generally not cost effective. Of course, it's possible that these were obtained late in the 6th generation Virtex lifecycle cheaply and repurposed for this.


Any other speculations?

I kinda want to buy one to see if it yields more clues, but I'm holding back because I know that the chance that I will go to the trouble of spinning a new board to take advantage of an already old FPGA is pretty much nil, and I'd have to remove them from whatever this is first.

for protyping an asic?

Ah, okay, then that probably explains it - likely a crypto miner board.

Maybe for a  Brute Force project like the https://www.copacobana.org

XCVU9P is massively used in miner cards.

1800RMB is the right price?
