PC: Thinking about selling my PC as a whole

Want to sell my PC as a whole and buy parts to build a Core 2 setup..

Antec Sonata Case (http://www.newegg.com/Product/Produc...82E16811129155)
Antec 350w TruePower 2.0 PSU
MSI K8N Neo4 Platinum Motherboard
Corsair XMS 2x512MB (1GB) DDR RAM (http://www.newegg.com/Product/Produc...82E16820145450)

I am not listing the hard drives or anything... I can price those myself because I don't know which ones I will keep...

Can someone give me a fair price on these components?

Thanks!
