s1gs3gv/biffa, thanks for the correction. My math brain was focused too much on stuff at work. I guess I shouldn't bitcointalk while working

I remember there being a number which initially went unsold, but then heard rumor someone bought them all out for less than MSRP. Rumor is rumor, can't found it, but some users did report being unable to purchase the remaining 900 the same day. Because of this, and wanting to project 'worst-case' scenario for planning purposes, I presume the full 2500 to be sold.
As to building miners for dirt cheap, if KNC's profit margin is similar to the Jupiter series,
they're making about 86-89% pure profit on the gear. So it could be done.. but.. the whole thing of they won't do it because they know they can just keep the money to themselves.
People shouldn't get into this game at this point with the thought of, my mining gear will positive ROI anytime in the near future. That window, for the most part, closed in 2013. Anyone mining now should have the mindset that they're banking on bitcoin value skyrocketing at some point.
Even still, it would be better to just buy bitcoin with your miner money.. and keep buying it if you believe the value will increase.
Mining is really fun though, so there's that. Can't say I'd drop several thousand just for that..
is to build the machines and then mine with them a couple months before giving to public.
Unable to pre sell to the public at inflated prices anymore, I doubt they can make mining gear at that profit margin again unless they can con more people as they are going private now, which is what the new strategy is I believe with the A series funding round.
