I'll second that. My HD 410 arrived today from the Dell Outlet and it did indeed have the HD 5450.
Got it set up quickly and it is rather surprising how well it runs.
There was very little bundled software on it, so much so that the only thing I removed was the McAfee trial software.
Another surprise was that it also included two disks, one with the OS reinstall disk (Win 7 HP) and the other with the bundled software so I don't have to go and pay for a set of disks if I want to do a clean install of Win 7 down the road.
