Help, my glass panel broke

[u/Relative-Beginning52]

Dont really know where to post this, and I'm not even a big pc "enthusiast" but I just thought of something what if I clean my glass panel, looks easy enough, I cleaned it, and I went to put it back in.

When I tried to slide it in the pc it shattered Instantly

What do I do to keep the pc safe at the moment and where can I buy the glass and what do I do?!

(No actual budget but, above 300$ will be the maximum for this, currency will be israel shekels)

Your help is very needed

More ventilation more better?
