This is a very basic bench power supply I made using a ATX pico power supply, a ATX breakout board, and a 60W DC power brick.
Basically all these components are not super unique, so any manufacturer will likely work. Just check dimensions.
I replaced the banana plugs that came with the breakout board because I didn't like them.

The pico power supply does need some modification. The clip on top of the connector needs to be snipped off so it doesn't interfere with the top print.
The Breakout board's LED and POWER switch need to be desoldered, rewired, and glued into place if you want to turn the device on and off more easily.
Assembly:
- Bolt on the banana plug replacements
- Glue on the switch and led with the wires attached to the main board.
- Remove the existing connectors from the breakout board and attach the board to the rest of the assembly.
- Connect Pico Power Supply and secure the DC jack to the bottom piece.
- The enclosure can now be pressed together and bolted shut. The bolts will thread into the plastic.
