How to seal my MSI laptop after opening it up?

[prefer93]

Hi,

I opened up my MSI GL 63 to install an SSD and when i closed it, it just wouldnt seal like how I opened it up. There's gap (1-2mm) at certain areas like near the USB ports.

I'm so angry now because i feel like ive damaged my laptop. One really small piece broke and came off which belonged to the case structure.

I'm paranoid to open it up and close again to avoid more damage to the laptop. The cover that protects the usb port seems to be damaged too.

So what are you asking?
If you are not going to open it up again to fix the problem, what do you want for advice?
