@ztex: I just want to ask, when we order the FPGA boards, would they be just "plug & play" / ready to run? Or will I need other parts? Basically what are the complete list of things I need to make this FPGA board run?
In order to plug them to a PC you also need a PC (cheap Atom PC is sufficient), USB cables, hub(s) and a power supply. You can place all parts an a table an or in a shelf and let them mine. The cost optimized 1.15x variant is prepared for larger heat sinks (59mm hole distance, e.g. Zalman ZM-NB32K or Titan TTC-CSC03) such that no additional cooling is required.
The FPGA boards have standard DC connectors such that standard wall plug supplies (e.g. from the supermarket) can be used. But this inefficient. Instead of this I recommend using a 12V or 15V Notebook PSU (for up to 10 FPGA boards) or ATX power supplies. Cut the cables and connect DC cables (e.g. this ones:

If you want it to be beautiful you have to build your own case with material from the DIY store (passive heat sinks and case fans).
