Neal... you should have called and negotiated with Dell. I recently ordered a studio xps 16 laptop and pretty much cut them down almost to cost, got about 250$ extra in savings including free 5.1 x-540 speakers and 50% off my next battery purchase (as i need a 9 cell but they don't got them yet). And that was on a system that was already discounted by about 500$ from their base list system. It did take 2 hours on the phone and talking to the manager a few times to get it.
Anyhow looks like it will be a good build.
