A simple ATX-based bench power supply using a few speaker posts and some 3D printed parts. Includes optional left and right handles and a pre-split faceplate if you need to fit it on a smaller build surface. Fitment of wires and components behind the plate is pretty tight as-is, I'd recommend adding another 40-50mm to the depth of the faceplate if you don't want to play "OMG, how is this all going to fit?" with the wiring.

Please be very careful when dealing with power supplies, those capacitors on the mains side can be deadly if you don't let them discharge. Only minimal changes were required on the power supply's case, we just needed to drill three small pilot holes that matched up with the face plate's mounting holes, then drove some self tapping sheet metal screws through. Just be careful not to use screws that will intrude too far into the case and hit any wires or components. ;)
