Selling Guidance for Xbox 360s

So basically I have one xbox 360 E original (non j tag) bought from Saudi Arabia, it has 2 controllers. I also got a xbox 360 slim cracked version. I have two hard disks, one is 500 gb and one is 250, both are full of games. In total there are 4 controllers. I also have the original Kinect for Xbox. How much do you think I could sell all this for?
