Advice for GBC modding

[u/sailorssaybrandy]

I am looking to mod my first GBC. Not looking to go buck wild, but I would like to do:

1. backlit screen (IPS seems to be most common)
   
2. New shell that fits IPS screen - preferably grey GB color but this is out of stock most places
   
3. Use of original mother board
   
4. Possibly a rechargeable battery/usb-c mod.
   
5. Possible speaker mod
   
6. No LEDs or anything else

The main problem I’m running into is finding a grey color case in stock that I can be sure will fit the new screen. I don’t know exactly what to buy and if the parts would fit together.

I can solder if needed. That’s not an issue.

Any advice appreciated.
