Here it is. An all internally powered S4M with a GTX 1080 in it. It wasn't easy, and to be honest I thought i was going to end up frying my parts with the custom power setup, but it all works! In fact, it works well!
In order to go brickless, I had to rethink how to power a PC that was this hungry. We've all heard of using the MeanWell power supplies with a PicoPSU, but those power supplies just don't fit in the S4M with all of this hardware in it. What I decided to do was to split the power load across two power supplies. Bel Power makes some dense and efficient power supplies, with more than enough power to supply either the GPU or the Motherboard, but not both. So that's what I did. The Bel 225W PSU powers the 1080 directly, and the 180W PSU is connected to a PicoPSU to power the motherboard. It's a tight fit, but with the 180W next to the GPU, and the 225W in front of the MoBo where an HDPLEX would go, everything fits. Barely.
The end result of 7 hours of planning, cutting, soldering, and crimping cable is that I don't need to bring a power brick with me to LAN parties, just a plain old power cable.
The parts list below covers all of the big purchases, but I used more than what's listed. About 25ft of 18awg wire, Molex crimping tools and connectors, a soldering iron and solder, heat shrink, liquid electrical tape, and other miscellaneous tools and trinkets round out the complete list of parts used to complete this build.
