Wanting to sell my computer, need a price

I want to sell my computer because I don't play games anymore and I have a laptop for what I do need a compute for. I'm about to go to bed, on my laptop so I'll give the specs of what I know off my head and will update tomorrow after school:
Processor: Intel core 2 duo @ 2.8 GHz, Core: 45nm, FSB: 1066 MHz, L2 Cache 3MB
PSU: 600w blue LED power supply, pretty generic but it runs stable.
Ram: 4gb Mushkin Enhanced 1066 DDR2 15-5-5-5 ram, brand new retails at 100$ USD
2 HDD, one is 270gb the other is 30gb for backup.
Running windows 7 premium.
It run's cool and looks good with 3 LED Lights (PSU, and 2 fans)
Generic DVD Drive.
All inside a NZXT M59 Case
It looks something like this, this isn't it just a picture I pulled off youtube... But something like this:

I won't be selling it online likely, if I do it'll be on ebay, I'll probably be craiglisting it or selling it to a friend so I can maybe get away with more then it's worth.

 

You can probably get around $300 for it, since Core 2 Duo is kinda old, and DDR2 is too.

Agreed. Anyone who knows what they're buying won't pay more than 300-350$.

Although, you could probably hock it for around 500-600 on Craigslist.
