Congratulations on your beautoful setup, I like this, i was always curious why fpga systems dissapeared so quick..now i know they never did!
I'm wanting a similar setup, my cards are so outdated,but would you be willing to share your software if I was to make the plunge hardware wise?
My plan is to release Keccak at the end of May, then Tribus/Phi/Skunkhash in June/July. More algorithms to follow every month. So yes you can buy the hardware then use my software, which has a 4% fee built in.
