you can flip the screen around so it faces up when the laptop is "Closed"
I don't know if you have enough room but if the laptop will fit in the space closed then it should work.
If you do it that way you shouldn't have to extend the cables
I did it on one of my projects and it worked great in the end (after a bit of work to get it apart and put back together again) and I can run the whole thing off the battery
It's a little hard to tell on this pic but the keyboard is right behind the screen, you just have to use a USB keyboard and mouse to work on it
