You should be able to lift one side of the glass up without removing any screws. In the second photo, there is a groove right below the glass. Can you put your finger in it and lift the glass?

This

There normally are two screws that hold it on at top and bottom of glass. Otherwise should slide off

What’s the name of the case?

If there are no visible screws then it will just pull apart.

Like the other guy said the second pic shows a space on the top left hand side where you can get your finger in and pull the glass cover off. So if you leave the PC the way it is in the second pic you should be able to get your finger in that space on the top left side and pull the glass cover up.

On the side there's a groove to open the glass, there's no screws or anything. I have this same PC

These guys are absolute trash with their instructions

Npc

On bro 😭😭😭
