question about selling

If I were to sell some hardware as a combo what do you think is a proper price for the specs?

Intel Celeron 1.8A
ASUS P4P800-MX
2x256MB DDR 333 in Dual Channel Mode

Well, when I try to determine a price for what im selling, I take Neweggs price new and deduct from that price how old and what condition the products in. For example, your mobo is $63.00 on newegg. If its a few months old try selling for $55 or $50. Hope this helps

thanks for the advice.

I prefer selling hardware for 90% of the new price, and lower it from there 2-5% ever couple days or when I see fit.
