Interesting that this only has a 90-day warranty. If you get it from the Dell Outlet, it will have a one-year onsite warranty.
This model is $508.97 right now direct from Dell, or you can get one for $396.97 if you drop the added 4GB RAM to have a total 8GB and drop the added 1TB drive and only have the 256GB SSD. I guess here you get a few upgrades in exchange for a short warranty.
