Need Help concerning trading in my PS3 60GB

[The Truth]

So, I'm wanting to take up GAME's offer here in the UK. I want to trade in my 60GB (Dont play PS2 games, or use mem card readers), pay £99 and get a slim.

When trading in my PS3 do I need to package in everything with it (like ethernet cable, USB cable,) or just the main components (like Console, power cables, controller)?

Thanks
