Just got my first ever MacBook - which I got off my wife after she got it a couple of months ago from eBay off a chap who'd owned it from new!
It's a late-2007 white 2.0Ghz Core 2 Duo model that the first owner had recently upgraded, it has 3Gb RAM, a new 320Gb HDD and a new genuine battery which currently has only 89 charge cycles on it Even came with it's original bits like the installation CDs, manual and the little DVD remote. Looks like its been well cared for too, it's in very good condition with the only obvious wear on the bottom of the MacBook.
Despite it running an older version of OSX it does all I want it to do, and it much better and faster than my old laptop (a relatively 'young' Sony Vaio from circa 2009). Very happy with it, runs very smoothly and quickly though might need another card reader as mine doesn't seem to work in it. Hoping it'll soldier on for a few more years, only concern is the screen backlight giving out after years of service already under its belt. Very happy camper so far
Congrats!
While 4GB can be physically installed, only 3GB can be seen/used by the Macbook. You could be in an SSD to replace the HD. That machine uses SATA1 toward the HD, so some of the performance gain of an SSD might not be seen. Replacing a 5400rom drive with a 7200rom drive might make a difference.
