This is the exact laptop you will get pictured in this.

7/12 I am uploading pictures from 18 of these units. I have to go back later on to see what kind of damage each has if any.  Most of these will get some kind of damage on the rear vents in the back which are made of copper. The price might go up or down (once I have time to go through these and look). $499 for a perfect one or close to perfect an dall the way down to $399 for one with major dents in the front base.  There should be no white spots very loose hinges etc as that is checked. most of these won't have dents on the top since m6600s are more prone to that.   
Battery will be in Normal condition (the best that is possible for the more expensive ones. The cheaper ones will have a moderate battery that still works pretty decently. 80% have normal batteries.. It comes with a Dell factory  Ac adapter.   Pictures are coming out a bit dark for some reason. Also some might show 4gb and someone took some ram out but will be upgraded to 8gb.  To upgrade to 16GB add $30. I also have 300GB SSD's available for these also. SSD makes it so much faster. SSD upgrade is around $60.

Specs of the laptop include the following:

Core i7-3720qm 2.6 Ghz 4 core 8 thread processor
8GB DDR3 12800 RAM
2* 320GB 7200 RPM Hard drives

Normal Battery (this is the best battery possible to put in it Battery can be Normal, Moderate, Low, Replace Now, Bad)
USB 3.0 ports, HDMI ports
8GB USB Dell Flash drive with windows 7, and drivers included

(windows 7 Pro back on it) Office Pro loaded(COA under battery for Windows 7 Pro) can install windows 10 Pro if you need but put in comment section if you like
