There is a v0.2 branch in that repo for the next revision, I will be getting those made soon and once they have been validated I will be production on those for sale like I do with the ATX2PCjr kits!
Despite the low side switching issue, I'm very happy with how this turned out. I made a lot of gambles in this design in testing a lot of new techniques for me and it worked great. I have the power switch sorted out in the next version's design so that will be fixed pretty easily. Getting the two SMPS's working was much more important.
On that note, these are not going to be easy to assemble for most people and cleaning them properly is very important. If I make them available as a DIY kit then it will be with a big disclaimer with no real guarantee.
