Display on project case

Thanks for the reply. Unfortunately buying a new case is not an option at this point. This is for work, and I am on a budget and don't want to spend any more money on it. I have 3x of them that have some similar defects.

That being done it doesn't have to look super pretty, just somewhat cleaner would be nice.

I used a Dremel to cut the holes, it worked but was a bit hard to control on the material. Any suggestions for a different tool?

The screen is this one, there are no mounting holes. I am fine with permanently adhering it to the case. Can this be done with any glues? Epoxies? WIll the solvents in them adversely affect the board?
