The power capacitor exploded
Online research and in describing the event to a friend seems to point towards capacitor issues, either in the PSU or on the Motherboard. Opening up the box I can''t see any issues with either visually: No capacitor tops popped, I didn''t see any smoke or scorching or oozing anywhere.

power supply
Therefore, a capacitor failing in this fashion would not cause any electrical shock hazards. If a Class-Y capacitor, also known as the "line to ground capacitor" or "the line bypass capacitor"—the capacitor placed between line and ground—fails short, this could lead to a fatal electric shock due to the loss of the ground connection.
safety
Disc capacitors tend to crack open if overloaded-the polarity does not matter. Unless you overvoltage them or reverse voltage them or have a high current ripple in the DC power line beyond the capacitors rating they are safe to use. I have had them (electrolytic can capacitors) explode in my face due to being installed in reverse.
Graphics Card Capacitor Explosion | Tom''s Hardware Forum
The reason why the capacitor exploded could be ranging from overheating, irregular voltage control, and other faulty hardware causing a irregular current flow through in the circuit. Having a PSU frying any hardware is quite rare, this is because the PSU and motherboard have built-in surge protection.

What would cause capacitor to explode? | Finddiffer
A capacitor is placed inline to your component and absorbs spikes in power, creating a constant steady stream of the electricity or voltage needed to power your component. What do capacitors do? Capacitors are widely used as parts of electrical circuits in many common electrical devices. Unlike a resistor, a capacitor does not dissipate energy.

Why electrolytic capacitors blow up
Capacitor impedance is generally expressed as the value at 20°C and 100 kHz. The impedance will be higher at lower frequencies. Storage conditions can also affect electrolytic cap performance. The leakage current in an aluminum electrolytic capacitor will rise if the capacitor is stored for extended periods.
