So after this upgrade I will have a total of $159 into the laptop. Rave for the free items on Craigslist and to those who give away perfectly good laptops because they can't fix them. :)
Update: Cloned original while the new one was encased in an external USB enclosure. Used Clonzilla and was running in no time. I left the main partitions as they were and created new ones in the empty space. It is really cool to have the extra space now.
