How much is this G5 setup worth?

Can someone out there please give me a price range (lowest-to-highest) as to what the following may be worth? Thanks!

Late 2005 model (Rev. C I believe, only 4 RAM slots)
Dual 2.0 GHz Power Mac G5
2GB RAM (2x 512MB Apple + 2x 512MB upgrade)
256MB VRAM (ATI X850XT from Apple)
160GB HDD (Stock)
Airport, Bluetooth
EDIT: forgot to mention the 16x DL Superdrive (DW-Q28A)

20" ACD purchased at the same time

1.5 years left of AppleCare covering both the tower and display. Original boxes for both.

Thanks again in advance for any insight!

Wow, it's sure depreciated more than I expected...anyone else care to share their opinion, regardless of whether it's lower/higher/the same?
