The costs add up. If you see, burnin's board is at about the same price point.

Setting up to build about 500 of burnin's or bkkcoins K16 board will set anyone back about $10,000 in parts (not including ASICs or the assembly house charge). This is quite a bit of money to lay out.

The K16 board will cost anyone about $65 if they want to go to Digikey and Mouser to buy all the parts themselves. Good luck soldering in those 325+ parts.
