What would this be worth?

[M@]

I'm thinking about putting together a new computer and wondering what I could get for the computer I currently have and some spare parts.

Computer Specs:
Lian Li V1000B case
AMD Opteron 165
Antec NeoPower 480W PSU
300gb Maxtor Ultra16 hd
BFG 6800gt with NV Silencer 5
1gb Mushkin 3200 (2x512)
X-Fi Platinum sound card.
4.1 Surround Sound speakers.
ASrock 939Dual Motherboard.
edit: forgot to add NEC 3550A DVD burner

Spare Parts:
Antec Sonata case
ASUS A7N8X-e deluxe motherboard
Nvidia GeForce 4200


I'm looking for what I can reasonably expect to get for these parts so I can decide if it's worth it to build a new system. thanks.

For that system I guess I would pay around $800 considering it is used.

around 750ish, might get more $$ parting it out.....just a thought.
