Is building a laptop as easy as building a PC?
Honestly, unless you want to do it just for the bragging rights, it's pretty much useless. laptop parts are almost always proprietary and will only fit/work with other proprietary parts. Even if you do mange to find individual parts, fabricating a workable blend to fit in a laptop chasis is next to impossible. Lots of time/money involved just for research and testing, and you could be halfway through and realize it's just not going to work.
