i know that this is not arcade related persay but i trust you guys and most of you seem to know your stuff

i am going to build a portable nes and write a paper about it for my technical writing course here at A&M and i was wondering if anyone here happens to have any suggestions of what i should build the case out of
i am not familiar with metalwork or plastics so i'm lost
i was considering buying a project box but they are not really ergonomic and tend to be fairly thick
i'm plannin on using a full size nes and a psone lcd if anyone is curious about the size or the route that i'm going to take
i decided against the nes-on-chip for legality reasons eventhough i'm fairly confident that it's not illegal, just frowned upon at best
any help with links or something would be great
i literally have no clue where to start
thanks
