TLDR: Broken Chassis on HP Pavillion 15.6 Gaming Laptop, Originally Plastic Case, Wanting to Know if I Can Replace with Metal Case
Hello,
I have an HP Pavilion 15.6 ec Gaming Laptop. There is an issue with the back case and front case, specifically the plastic near the hinges cracking and deteriorating. I took it to a laptop shop and they confirmed this issue, they are charging me more than what they repair should be.
I am planning to do the repair at home on my own, but I would like to know if the replacement could be done with metal cases, and if so, where would I be able to make such a purchase. For now if there are no options for this, I will go with a plastic one
The cracks in question:

Simple answer, no
Long answer: most consumer grade laptops are specifically designed the way they are and you cant get custom metal replacement parts without contracting a metal 3d printing company. Honestly you are correct, most repair companies will charge large labor costs to persuade you not to get it done with them as it’s a time taxing repair pulling everything out and putting into a new case.
If this is a common issue for your laptop then suggest getting another model.
