Started watching that last night (1-3) and it is good and kept our attention. I'm going to take a look at the other one (Survivors) mentioned as well. Thanks!
If anyone was considering buying an M4 Mac Mini, you might want to reconsider. Read a poor experience/review of this on diyaudio, from a user who has an M2 Mini which he has been very pleased with (as am I of my M2 Mini). Here is the thread:

Check the Do It Yourself thread. There aren't any white papers or build guides available. There are gerbers for the boards (check the Stax thread for the location for board files and for schematics), and you should be able to find BOMs, etc. though it might take quite a bit of reading and effort. The board search works well for that (searching a thread).
