Please mention the word "Supermicro" in your text or email response, as I am selling multiple computers currently.

Up for sale is a beastly, high-end server or workstation PC for video editing, machine learning, light gaming, and development. It comes with the tower and power cord only. I will deliver between Sunnyvale and South San Francisco for an extra $20, or we can meet in San Mateo or Palo Alto for no extra fee. 14-day money back guarantee.
