I currently have a Lenovo b450. It's almost five years old, and has a meager 4 gigs of RAM. Dual core with about 2.8Ghz each, and about 500G of storage from both hard disks. The battery is kaput and the graphics card is from Nvidia.


Anyhow, I'd like to know if it's possible to rebuild the laptop, switching out the motherboard if necessary. Because I'm fairly certain I have reached the maximum this laptop can do, but it still is still slow by today's standards. If a empty laptop case is going quite cheaply, I'll consider that as well.
