How much should I sell My Xbox 360 for?

I Have A Perfect Xbox sitting on my Shelf, All the hook ups for it and all. Two Paddles (White and blue), And About 21 games.
I was thinking about that Maybe If Someone buys the Xbox with all the games and all the memory on the Hard drive I should Probably Raise the Price Of it up Seeing as how He or she is going to be playing with all the saved Data on it and left off were I Stopped. And maybe Lower or keep the usual price the same If the memory is deleted.
The games are:
Left 4 Dead
Call of duty Modern Warfare 2
Call of Duty World at War
Resident Evil 5
F.E.A.R. 2
Rainbow Six Vegas 1 and 2
[PROTOTYPE]
Doom 3
Terminator Salvation
Rockband 1 and 2
Guitar Hero Metallica
Farcry 2
Saints Row 2
Conflict Denied Ops
Madden 08
Black Site Area 51
Sonic Unleashed
Ultamate Alliance

So what do you Think I should sell That Thing for? Need some hints and Ideas about it Please and thanks.
