8 Spartan-6 LX150-3FGG484C FPGAs:just as ICARUS X4 on one board,you can use ICARUS rom and software.
USB interface for configuration and mining communication.
Power supplied through 6-pin ATX PCI-E connector(min 100W ) .
1.3 GH/s guaranteed, 1.6GH/s typical.
85 W power consumption measured at 1.6 GH/s (more measurements pending).

To power the board, one can use either a standard ATX power supply with a spare 6-pin PCI-E connector. Note that the rev3 board has headers to power 8 fans. If these are used, be sure to include the power consumption of the fans when choosing a suitable power supply.

Creating a Bitcoin client that fully implements the network protocol is extremely difficult. Bitcoin Core and some of its derivatives are the only known safe implementations of full nodes. Some other projects attempt to compete, but it is not recommended to use such software for anything serious. (Lightweight clients like Electrum and Bither are OK.)

So, $2000 for 1.6GHash? Rip off. You could build a 7970 GPU mining rig for the same hashrate for half the money.

The point of fpga is low power cost for extended use when difficulty rises. 85w for 1.6gh vs about 700w for GPU. Just as I would not recommend making a gpu rig I would not recommend investing in a fpga rig right now. Difficulty is set to double and then triple in the next few months. With a long ROI neither is particularly attractive
