A:AnswerThe GPUs are completely random based on their stock, for example, you could get an evga 3080, or a gigabyte 3080, or Asus, MSI, etc. Yes, the CPU is liquid-cooled. You should be able to find that information in the specifications tab.
A:AnswerYes, you can connect to wifi and ethernet the pc comes with that. It does come with a power cable, all pc's do. It does work out of the box, but if you face any issues, you should contact geek squad or CyberPowerPC. It does come with a keyboard and mouse but I recommend getting different ones because the included ones are trash, but the bare minimum. You obviously need a monitor. Your welcome. :)
A:AnswerUnfortunately no. I think we can all agree that for $2799 we'd rather have a better processor like a Ryzen 9 5900x and a better gpu like a 3080 ti or a 3090 possibly instead of a 3TB HDD. Maybe also lower the price or put towards better cpu/gpu with only 16 gb ram.
