In one Job, we had a glass cabinet holding curiosity items. One was a graphics board where there had been a bubble of air in the packing. The ceramic block which was the GPU had, at it's center, a big crater down to the silicon. You could even see the bonding wires. That thing blew it's top so hard the fan ended up halfway through a network card (exhibit B).

I've seen some documentation from government destructive testing. One of my favorites was pictures of "this is what happens when you connect 220VAC across Vcc and ground on an 8080 CPU."

Let me guess: Thingy Go Boom?
 
One of the technicians where I worked wired an electrolytic capacitor in backwards. When the engineer turned the power on, the top of the capacitor blew its lid and sat there with a little candle like flame flickering. He had to call everybody into the room to see it.

Only engineers do things like that.
 
Ahh, yes, it seems You get the pictures that came to my mind when I realized what I had found. ;)

Solidified while falling? Very tidy, near spherical looks like.

Touching anything nasty?

Acctually swashed up through an unused hole for the outbound wires - one of those where I solder in my pimpwiring. If I had'nt had the idea to move that from the decommissioned unit to this one...

Googling 'pimpwiring' leaves me none the wiser .. unless you mean the Leder Body Belt Leg Garter Punk Gothic Thigh Pimp Wiring, in which case where do you attach the power?

There might be a something that might nearly fit a power socket. Maybe this runs directly with 320Vss AC? I think it was said that one use lasts you a lifetime.
 
Would nosnake_enable="YES" help in this instance? (See attached picture).

I'm not sure what I see there.

Apparently a snake, of some denomination. I recall seeing photos many years ago, of a snake comfortably entwined within the confines of a power supply unit - a much bigger snake than the attached picture shows. It must have crawled in when it was young, liked it there, and stayed till retirement.
 
HP used to use a crap 350w supply in their desktops... well known to blow mother boards when the PSU failed.
I only install the premium PSU in my own, and client machines.
The few dollars saved on cheapies or no-names is simply not worth the risk.
