The motherboard alone is too big for the laptop case for starters. that's not adding a cooler, the GPU lying flat or not, RAM, etc, just won't fit , no way, no how. Period.

Then things like the keyboard isn't a standard USB connector, just so many things that this won't work.

For the amount of money spent, buy a laptop if you want a laptop. And the whole batter/power conversion thing, lots to do there.

Start off small, put a raspiberry pi inside a case and make it portable. costs you $35 and you'll learn instead of dumping hundreds into something that won't work.
