Cyberdeck

So I'm working on my cyberdeck and I've got all the components and set up everything fabulously... but I decided to build the case, like draw it on autocad and lasercut the pieces and build it with glue or screws idk

Anyway I'm worried like either I won't like the design anymore like I'll change my mind or I'll forget a detail or mess up the build...

I'm also considering like if I don't end up building it then I just get two briefcases of different sizes and put the big screen in the small top half and then the keyboard and pi and stuff in the bigger bottom half case but honestly idk
