Your computer doesn't fit the mainstream categories: it is too "custom" for most business/professional usage, but the extra RAID card and NICs aren't usually worth much to the gamer market. You would probably get the most out of it by selling the parts individually. As a package, I estimate that you could get between $350 and $600 for it. If you can find someone interested in just your configuration, you could, of course, get more, but the market of people willing to pay for all of the parts you include is very small.
