Help selling a PC

[shadykidd]

In the next few months, I plan on selling my Alienware PC, which is nearly 3yrs old. Here is a quick rundown of the specs:

-Saucer yellow Alienware case with matching keyboard and mouse
-P4 3ghz w / HT
-1gig RAM
-GeForce5900 Ultra 256 MB
-Plextor CDR
-120 Seagate Barracuda HD
-19" NEC CRT Monitor

I am not sure of what fair asking price for this would be. I have scene some Alienware cases, just the cases, going for 200+ on eBay.

I was planning on asking $700 and seeing what kind of response I get. Does this seem fair, am I overcharging, or am I cutting myself short?

Thanks for any advice!
