Can someone help me determine what my PC is worth?

[LeprechaunKing]

I am trying to sell my PC so I can upgrade. Can anyone tell me if this is about the right range?

Abit KT7A-Raid mobo
1.2 GHz Athlon Thunderbird at 100 MHz
1 512 PC133 Samsung Memory
40 GB hard drive
GeForce 3 (original, not mx, or otherwise)
Floppy drive
Antec case with 350 watt power supply
Generic CDRW
Seeing as these are all used parts and all, is 250 a good price, or what should I do. My friend is buying this PC for his parents, and he has built several computers, so he knows what parts are worth. What is a fair amount?

Thanks for any help.

200-300 unless you find some moron, then 500-600
