its not that hard to put together a pc and no you cant make a laptop
lol, you sure about that? I've put together a laptop before, also a couple bread-box machines (breifcase-sized PC w monitor, keyboard, battery, etc) It's not as impossible as you think...
You just need to source out a chassis and all the components (mobile processor, ram, storage, etc)
Lots of companies make barebones laptop chassis; you just need to know who to talk to.
