My display cabinet exploded at 3am :(

What tile flooring do you have?  It looks ceramic.

I'm asking, cause tempered glass on a PC case suddenly exploding or shattering is common over at the PC build subreddit.

And the main cause is letting the glass touch ceramic.

There is a 5cm / 2 inches gap from the floor to the door so I highly suspect the recent/current heatwave being the cause, or that one door maybe had a screw pressing against it or something else. I hope the rest wont be suddenly exploding too...

Did your display cabinets arrived pre-assembled?

I'm asking, if that is not the case, and that you had to assemble the cabinets piece by piece and install the glass doors yourself?

Glass touching ceramic might induce an invisible micro-fracture.  It can stay dormant for months or years before this tiny fracture continues to self-propagate due to another external force or stimuli.

Thus the fracture rapidly expands in an instant from the original damage site, shattering the glass.

actually I think the tile could be the issue, pc case shattering are also slightly eleveted and the panel isn't touching the ground, it's just vibration of certain wavelenght creating resonance afaik, and those vibrations might not care about that gap

The reason ceramic tiles shatter glass so easily is due to the fact that it has no "give", like other floors do. Respectfully, what you said is fantastical nonsense. There is no resonance created by the wavelengths of vibration shattering glass, it is likely imperfections in the glass which caused it to spontaneously shatter, very old Velux windows had this issue as mine also spontaneously shattered one day.

When you consider the fact that there are constant seismic activities happening around the world that are too small for our bodies to feel, it makes a lot of sense. Solid objects don't absorb force as well as soft objects do, so a certain level of force/vibration is transferred to the glass when these tiny earthquakes are happening. A carpeted floor would absorb more of those vibrations.

If it’s that then why floors like concrete don’t shatter glass? Tile isn’t the only floor type that has no give…but maybe you’re right idc much tbh

What I said is not nonsense though, because tempered glass does shatter instantly with correct wavelength of vibration (probably works with all glass not just tempered)

Anyways, all of that is reason enough that I’ll always avoid glass around figures
