I am very aware of the healthy skepticism of most if not all of you. I therefore kindly ask of you not to spew out the fact that its impossible to build a laptop at me but instead attempt to help me to make this somewhat possible for the next person interested in the idea.
I already have:
somewhere to buy a screen: https://www.laptopscreen.com/English/
somewhere to buy a motherboard, CPU, GPU, RAM, storage and other things although I would be very interested should you recommend other places where I can get these
I will build the cooling system myself
somewhere to buy a laptop shell (I am aware of how difficult it is to find one and am therefore very flexible on all other components)
somewhere to buy a power supply
Thank you very much for helping me and pushing the possibility of building a custom laptop ever so slightly more realistic
