What's Next When a XPS 9310 2-in-1 Survives a 3 Foot Fall on Concrete

Before the stories below - yes, the XPS 13 9310 2-in-1 survived, and is durable! Built Solid! I am surprised!

After close to four years of no issues, my first and only XPS had to slide down the car bonnet and slam onto the concrete at a height of about 3ft. At first sight, nothing seems to be damaged. As I picked it up for closer examination, the damage includes:

1. Broken top right bezel of screen

2. Bent Closing Case

3. Damage to right corner of laptop.

4. Minor crack on screen. 

Good news is:
1. Screen works well

2. Touch works well

3. Hardware test ok

4. Speaker now works (previously didn't work)

Issues found upon further use:

1. Reads WiFi but limited speed / "can't locate DNS". Suspect an issue with the antenna. WiFi works perfectly intermittently. 

2. When there is Internet Issue, even LAN > Type C does not work. 

3. Full hardware test returns no issues.

4. Opened up the laptop, see no visible damage, and looks like the network card is built in. Is this going to be a problem?

Solutions / Ideas Requested:

1. Replacing Closing Cover

2. Replacing bezels? or does it come with the screen?

3. Any cheaper options to fix the damages stated.
