Good question - I started out wanting to try electrolysis versus the more manual methods of rust removal when working with vintage machinery rebuilding. Now I am in stubborn mode . I have read literally dozens of how to's on the web relating to converting a psu to a bench top power supply - simple steps 1,2,3 and done. I have no idea why this one is so difficult.Do you want to try electrolysis or anodising out of interest or to use it regularly? If the first, I can see the appeal in spending hours futzing around trying to get something to work that isn't supposed to do what you're trying to make it do. If the second, just spend $60 or 70 on a 30V10A powersupply from Amazon. I tried the cheap approach and wasted a bunch of time and effort. Bought a powersupply from Amazon 7 or 8 years ago for $70 and have used it literally 100s of times. It's even useful for other stuff, like testing DC electronics and LED lights.
