This is very tentative. I'm thinking of downgrading from my current setup to an imac because I am just not making use of the MacPro power and could do with a bit of extra money. Edit: I am tentatively interested in offers and trades (24" Alu iMac only) as well as any more estimates. So: Mac Pro 2.66 Quad standard setup with 3GB RAM, an additional superdrive (the second drive is NOT DL), and AppleCare good until Jan. 2010. Dell 24" 2405 - purchased new in May 2006. Both are in as new condition. I think I need to add that the machine comes with the original disks - Tiger OS - and all original packaging etc. Also, I have to move every few years so if you offer a trade, I would need you to be able to ship in original boxes.
