My daily use desktop for sale after Oct. 30th because I'm leaving. Pickup by yourself in Palo Alto. It's powerful enough for playing most existing games fluently under high quality as well as running some deep-learning demos or inferences. I built it up in November last year and it's still in good condition.

A built-up gaming tower with similar accessories costs more than $800 on amazon tax excluded and now it's only $500. The price can be further discussed if you really want it. You can also have a 24 inch monitor for $50 and a gaming mouse for free if you like them (notice that the keyboard in the picture is not for sale).
