A computer my friend is selling, how much would it be worth?

[The artist formally known]

-Cooler Master ATX Case 
-Antec Quiet 480 Watt power supply 
-Gigabyte GA-M61P-S3 Motherboard 
-Socket AM2 AMD Athlon 64 Bit Dual Core 6000+(Two 3GHZ Cores) 
-PCI Express ATI Radeon 2400HD Pro with 256MB of DDR2 Memory(VGA AND DVI Out) 
-Western Digital SATA 2 500GB With 16MB of cache 
-2GB PNY XLR8 Dual Channel DDR 2 800MHZ Memory(SLI Ready)(Has Two Open slots, Upto 8GB) 
-Sony CD/DVD Writer. 

The PC has: 
-(6) USB 2.0 ports. (4 in the back. 2 in the front.) 
-(1) IEE1394 Fire Wire Port. 
- 6 Channel HD Audio Out 
- Also has onboard video. 
- (1) Parallel Port 
- (1) Serial Port 
- PS2 Connections for keyboard and mouse. 
- Dell Keyboard and an optical mouse. 

It comes with a 19" KDS Flat CRT Monitor that has a trinitron tube. 
It also comes with a Altec Lansin 3 Piece Speaker system that sounds great

The power supply has a quirk and there is a delay before the system turns on after you have pressed the power button, however the power supply will be replaced. 

Operating system is not included.

I wouldn't need anything but the tower, meaning speakers, monitor, keyboard and mouse are all useless to me.
