Additional notes: I took the case apart and checked the power supply. I'll also add some notes about the shipping date. * Orders placed by 6:00 PM on June 29th will be shipped on June 29th. * Orders placed after 6:00 PM on June 29th will be shipped on July 6th. This is because I can only take the packages to the Kuroneko (Yamato Transport) store on June 29th and July 6th. I apologize for making you wait nearly a week for shipping depending on when you purchase. Also, I have adjusted the estimated shipping time to 4-7 days accordingly. This is a custom-built PC. I rebuilt it using parts left over from when I built a new PC. I'm not sure of the power supply specifications, but I think it was around 450W to 500W. → The power supply is a Seasonic 520W power supply (added 2024/6/25) Also, as you can see in the photos, it has a DVD drive. However, I forgot the model number.
