I am planing on building my own system this time and want to sell my old system to a friend but do not want to rip them off. On the other hand I want to get what the system is worth as well. I have a 3 year old Alienware P4 3.2, 2 gigs of ram, 460 watt PSU, EVGA 7600 card with 256 mem, 120 gig HD, Abit MB, DVD burner, Sound blaser audiology. How much is a fair price for both I was hoping for $500 or at least $450. Thanks for any advice looked on E-Bay but they did not have my exact specs saw one for around $500.
