burnin,
I know it was mentioned earlier that both versions (10/20 chip) use the same pcb but will the 10 chip version come with support components placed and soldered for the other empty chain? That way we could at a later time add 10 more chips without having to place all those pesky smd parts and just reflow the chips.

Or maybe we can order a special 10 chip version or order the 20 chip but only solder 10 chips. Or this is a dumb idea...just wondering because many of us have an "extra" 10 chips.
