PRICE CHECK: How much would you sell these for?

Hi all.

Considering an upgrade to my system as I nabbed some cheap DDR3 RAM in the play.com sale a few weeks ago. My question really is when I upgrade what I should do with my existing Mobo/RAM/CPU/Cooler....

If I can get a good price for them (either together or individually, I'd rather sell together though) I would probably sell them but if I can only get £50 or less I'll probably hang on to them as spares/ 2nd another machine

My parts are as follows: Intel E6600 (2.4ghz), Asus P5B, 2GB Corsair XMS2 800mhz CL5 and an Arctic Freezer Pro 7

What dya reckon?
