How much could I sell this old rig for?

Bought it a while ago off a generous friend for $150. How much would this go on eBay or something?

Specs:

Graphics card: NVIDIA GeForce 8600GT

Processor: Intel E7200 @ 2.53 GHz

Memory: 2GB RAM

OS: Windows 7 64 bit

I know I didn't really go into detail. But if theres anything else you need to know to appraise it, please tell me. Thanks :)

Bout the same you bought it for, maybe.

id say it could go for a good $350
