Top of PSU - the insulation on the inductor is not paper
Bottom of PSU
This is a PSU from a Infrant/Netgear ReadyNAS NV+ system. The PSU likely failed because of design problems instead of faulty components; the failure seems to be a common event on certain manufacturing batches.
Notable features on upper picture: 3 bulged capacitors, 1 inductor with burned insulation. Notable features on lower picture: signs of overheating, jumper wire in solder.
