Why do you think the glass shattered? Someone probably sneezed or dropped a bagel and there was zero dampening in the room whatsoever, causing massive reverberations and the glass to shatter, er, relax
found this out the hard way about 15 minutes before leaving for the airport, while in the process of moving to a different country. never buying a glass case again.
It's also bad for noise dampening and EMC. I decided I don't need my feet to be illuminated in all colors of the rainbow under the desk and went with an all-metal case instead.
Gosh, you must have been startled by that. Tempered glass terrifies me because it feels like it has demons inside (that's why it explodes so violently when the seal is breached)
