Maximum PC

To start this off let me just say that I want to be fair in the price that I will post this computer for locally. I live in Alaska and I am going to post to craigslist here.
I have already looked up what all of the gear would go for if purchased used at Amazon.com and every piece that is in the rig could be bought there used. They were all in stock. I am going to post what I have and it is all assembled and in good working order with a clean install of Windows XP Pro. The OS with serial is genuine and has been activated. I have done all of the updates to the OS and have installed the free version of Avast Anti-Virus.

This is being sold without mouse, keyboard or monitor.
The price for the used parts at Amazon.com totals out to $710 which I know is too much to ask for a rig that is 3 years old.
I am thinking of asking $400 for the rig as they are all quality parts and it will still do a fine job of gaming and the case
and PSU will be good for a long while yet IMO.
I am looking for opinions on pricing and advice on possibly how to market it for selling.
Thanks in advance for any responses.

I agree with that assessment. I posted prices from amazon.com which were half of retail value or in some cases lower and it totaled to $710. If I parted this out on eBay I could conceivably get those amounts. Selling it as a built rig is what I am looking to do and $710 will never happen. Do you think that selling it for $400 is reasonable? I have seen deals with comp, monitor, mouse and keyboard for $400 with faster processors and twice the memory. Not a bad deal if you never want to be able to upgrade and don't care that the case and PSU will be junk but that is what people will be comparing it to unfortunately.

Thoughts?
