There are some Lenovo tiny PCs on sale at good prices -- I ordered a new one for almost the same price ($2 difference) as the best price I found for the same model refurbished. Plus, I could do a little customization (you can do more -- I basically deleted the mouse and keyboard, added the toolless chassis and a (built-in / punchout) VGA port (as opposed to a VGA dongle, which is another option).
The models that are on sale include: M75Q Tiny (base price about $342) M75Q Tiny Gen 2 (base price $401) M90 something one other -- don't have the number at hand Oh, actually, there are a lot more, including full size desktops, laptops, all in ones, ....
