Actually just posted this same computer for $600 a couple days ago but I went to the Apple store today and got a brand new keyboard and mouse pad section. The mouse pad was stripped and hard to use before so I was only gonna ask for $600 but Apple replaced it for free and checked the whole thing out. There is nothing wrong with it at this point aside from a two year old battery you might have to replace down the line.
Processor is a 2.4 GHz Intel Core 2 Duo
