are these refurbished by HP or a third party?
I have order 3 HP desktops from Woot that were refurbished and it was done at HP.
Your mileage may vary.
Factory reconditioned: By the manufacturer or someone they designate.
Refurbished: 3rd party
Here’s the official definitions.
A “factory reconditioned” item was returned, inspected, and restored to fully working condition by the original manufacturer or a certified partner. And the original manufacturer stands behind it with a warranty. It’s as close to new as you can get without technically being “new”.
Refurbished covers everything from buyers’ remorse returns and products whose defects have been repaired by the pros to damaged packaging and discontinued items. If you can accept their checkered past, refurbs have a lot of love to give.
good to know, thanks guys 
Now, anyone know what the build quality is like on these pavilions?
