How much is this Dual G5 & Display worth?

[methodmano]

A guy I know at school is selling the following set-up for $2400:

He bought it in Fall '03. No Apple Care.

Dual 2.0GHZ G5
2.5GB ram
128mb ATi 9800 Pro videocard
SuperDrive (not sure on the specifics of this)
160 GB hard drive
G5 Keyboard (used, so not completely clean)
Logitech MX510 Mouse (best mouse IMO 1600DPI precision)
ADC/DVI switch

23" Cinema Display (aqua plastic, not aluminum)
No dead pixels. Very little light leakage.

Boxed retail copy of Tiger (os 10.4)

$2400 seems a little high, but it's been a while since I've bought a new/used computer. Please let me know your thoughts.

Offer him $1800 and go from there.

So, this set-up is only worth $1800?
