@jmorris @oshpark @rgilton This is actually "cheap". I was quoted something like $6.9K for an American fab to make a very similar specced board (but I think that one was only 8 layers not 10).
But when you add in the additional $1K-ish of components I'm putting on the board, the custom rackmount chassis, another $1K or so of custom semi rigid cable from PCB to front panel, etc. this is going to end up being one of my most expensive projects to date.
