How to convert an ATX power supply

PSU build

10mm ply (3/8") should be thick enough after all you need to screw the belt clamps to it. I don't insulate mine and I use MDF at 55C for PLA it's not hot enough to burn it

I just ordered a 12V 20A Switching Power Supply off ebay that should be good enough to drive everything - for $28
