You cannot build a new laptop in an old laptop chassis. The things just won't fit. If you want to go the route of "building" your own, you should look at the "barebones" laptops Where all of the customizable components are up to you to choose: processor, HDD, RAM, etc.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
