How much should I sell my Xbox 360 for? Details on what I have?

I have a Xbox 360 console w/ hard drive. I have had it for 10 months and it still has the 2 year warranty on it.
What i have with it:
-good condition Xbox 360 console
-Hard drive
-Gamer profile with XBL account and 3,000+ gamerscore
-1 wireless controller
-Headset
-Ethermet Cable
-Componet HD AV Cable
-Power brick/cable
-Rechargable battery pack
-Plug-N-Play charger
-Nyko Intercooler
-Halo 3
-Madden 2008-Xbox 360
-Condemned-Xbox 360
-Halo 2
All games, extras, and Xbox 360 are all in great condition. How much do you think i could sell this for?

basically all the stuff down to the rechargeable battery pack comes with the pro 360. Which sells for 350 new. So since it is used and the games aren't that new, i would say 350 dollars for all of it. That is as high as I would pay.
