This open-frame design can optionally be mounted in an enclosure of the user's choice. There are many "how-to"s out on the web encouraging people to hack open a surplus computer power supply and put binding posts on it for providing a simple, high-capacity supply offering +3.3V, +5V, and +/-12V rails for general electronics lab work. However, the option of hacking into your ATX PSU has some serious draw-backs:
- Safety isolation clearances may be compromised, potentially risking life and limb;
- Once you've hacked the PSU, it's no longer able to be put back into use as a computer power supply.
Ergo, the solution here is to provide a break-out board with an ATX header and necessary on/off circuitry as well as standard-spaced binding posts for plugging in single or dual banana plugs. An additional novelty of this board is the unique plated slots around its edge, which are used to clip on "alligator" style test leads as well.
This project is already complete, tested and boards are in production - it just needs to be approved for sharing on Elektor Projects. See the design description and photos of the finished product at http://jordandsp.com/ATX-bench-top-power-supply-adapter.php

This is a great idea. ATX power supplies are very cost effective compared to similar units for the embedded market or for lab use.
However I'd like to suggest some improvements to the design:
