ATX based Lab power supply - 10th year anniversary edition

I had published an ATX lab supply conversion about 10 years ago. It inspired a lot of folks to take their first steps in hobby electronics through that instructable. And now there are many many examples of people doing the ATX conversion on youtube, instructables, etc. My original ATX conversion got packaged more professionally with an added ampmeter which was really useful to have. In the 10 years since access to cheap electronics modules on ebay, Amazon … has improved by leaps and bounds. I had used one of these variable power supply modules in making a nice little variable power supply but this only supplied 25W. I was toying with the idea of adding higher voltage to my old ATX conversion, at least to 40V. I ordered two of these power boost power supply modules through ebay at approx $10 each with specs of settable constant current and voltage to 60V with a low volt input. At the same time I also ordered a low voltage variable supply module and some of those incredible littlle volt-amp meters.”
