10,000 Avalon chips will be a lot of GH/s.

The board design will be really simple - Avalon are even going to be providing a complete reference design in May. So it'd be a 1 hr job to order some PCBs and then a whole bunch of skillet reflowing (or contract a proper assembler). Hell, for 6 figures you could buy your own pick and place machine and build them "in-house".

Having said all that, I'll happily take 6 figures for a couple weeks work  .
