With respect to your quote "I've had to relearn skills I have not used in 20+ years (back when I was first in the Navy) in order to change components in an effort to get these boards to run at speed.", this gives more context to PM's I've had with the user that, in my mind, validates the fact that they have been previously employed at Butterfly Labs and have insider knowledge.
Furthermore, "At that point in time, there was an order placed for 4000 boards to be built into a new type of unit that had just come out... the 250/230GH rack mount. This is what was being built during the time frame that nibbknot claims we were building Monarchs." would seem to be a plausible explanation assuming someone, in-fact, placed an order for 4000 rackmount units.
They may well have been an employee, but if they were, they were either completely clueless about the product being produced or are upset at having been let go. When I first saw the OP, I thought had a good idea who it was, but then there was the comments about the wife and then the kids and then the sick mother... The person I thought it was wasn't married... but after all the other lies I've seen him toss out there, those now become suspect as well.
