While on ebay seen someone selling 11Th/s of Bitfury boards

http://www.ebay.co.uk/itm/HUGE-Bitcoin-mining-ASIC-RIG-25-x-Bitfury-Miner-Full-Kit-speed-11-TH-s-/221319977317?pt=LH_DefaultDomain_0&hash=item3387b2d965

25X Bitfury

What would be the max price to pay for this ?

Also why would one sell so much when it could generate so much @ current rate.

Anyone confirm this seller ?
