Disassembly Notes
Please watch the disassembly video here: https://www.youtube.com/watch?v=YTJg4chGKNQ (Power supply comes out at 19:21)
For this power supply (at least on mine) there are four metal rivets holding the case on. The easiest method is to use a chisel and hammer to break them off. One in, there are three T10 screws. For the fan press down on the locking tab and remove the two cables (red goes into the closest to the resistor and diode for reassembly). To remove the round cable thing, you can try to use pliers to squeeze it out, but I eventually gave up and bended the metal tab to make it easier to remove.
