Zach;
About a year ago I got the Dell Dimension 5100 very similar to Zach's. I found that by calling Dell and telling them what I was looking for I got one heck of a deal with all kinds of software, etc, etc for about $1400. Also check the Dell site as to what organizations they give discounts to and also check with the orgs you belong to. I got an additional 10% plus some free extras because of my MOAA membership. A little research will save you mucho money and Dell support is excellent. Good luck.
