I'm in!
The render on page one appears to show this keyset in a Unicomp 122-key case and a GH-122 PCB. That case is ~20 bucks, and a small run of the PCBs would be around ~50 each. 120 switches are ~40 from sennin32. With a Teensy and shipping, say $150 (without a plate) for the keyboard ready for keycaps.
Go, man, go!
