Actual runtime + setup time on the case was ~70 hours (100 if you include the fixture) because I had to do 7 different setups and a lot of shifting and checking with my dial indicator until it was where I wanted it.
The whole thing was machined on a Haas mini mill, 16" x travel the case is 17.7" so that was what took so long. Also cutting the really small radius for the key switch cutouts took forever. The keycaps took a bit but not nearly as brutal as the case because 6 could be done at a time.
It "only" cost around $300. Most of the material was donated so that helped. Total BOM cost would be another $300 too.
