Ok, now some decent electrical wiring and a tiny bit of electronics work. The electronics for the regulator and screen are built into one device, which one can buy as is, no credits there for me. But all the rest is my own work.
It still needs a frame cage around it (which still needs painting), but it's now fully functional:
3.3V and 5V fixed, up to 24A each, one 12V fixed, up to 18A, one USB port (fast charge capability), and the ports under the screen provide 0-30V with up to 6A. The voltage and current for these ports can be regulated in increments of down to 0.01V and 0.01A.
All in all, if I didn't go fancy with paint and other visual bits, this would be around $100 plus labor. If bought "new" in a shop, such a device can easily exceed $500.
The heart of it is, like mentioned in earlier posts, a second hand computer power supply (ATX), something around 200W would easily do the job - mine is 600W, which is pretty over the top, but it's what I could get my hands on easily.
