Unfortunately, kiwi did not finish this project. So I have finished the software and designed my own SMC board.
Have a look here: https://www.tonymacx86.com/threads/mactester57s-imac-g5-17-a1058-model.130197/ The SMC kit in the first post includes software (Arduino sketch, libraries, Xcode...
Hi,
sorry for the late reply. The supply cap is 1000uF / 6.3V.
The coupling caps on the PCM2704 board were bridged, because the amplifier board also has coupling caps.

BTW: I've added a Cube review video to post #1
You made a great progress so far!
To prevent your USB hub from smoking, have a look here: #54
Does the WTV020 module work, if wired outside the SMC board? Looks like you already added the missing GND wire. The SD card compatibility is a bit of a problem.
To rid off the Audio hum, have a look...
Well done! :thumbup:
It's a rocket, but I still feel comfortable with my NUC based "HemiMac" mod: https://www.tonymacx86.com/threads/mactester57s-hemimac-g4.104625/
I think, you should start with an easy standard case or a G3 or G4 tower. They are relatively easy to mod.
Good luck

BTW:
here is the newest video, showing my iMac G4 "HemiMac" and the G5, running Sierra 10.12
Thanks for the mention. I'm glad, that my video inspired you:
I think, that this fat GPU will not fit inside the cube. Also keep in mind, that cooling is a critical point in a Cube.
I would recommend to start without a dedicated GPU and use the integrated GPU instead. They are good enough for...
I have now finished a new "2.0" version of the Pro Speakers USB conversion
It uses a PAM8403 Class D amplifier board. They are available for about nothing on eBay. The audio signal comes from a USB sound adapter. The sound quality is much better than with the old version.
Attached are some...
