Old PC Valuation?

Hi, I've recently upgraded my pc.

I was wondering if anyone would be able to help with a Valuation of my old one?

Specs are:
Case: Corsair 4000D Airflow
Cass Fans: 4 x Corsair LL120 RGB
Motherboard: MSI MPG X570 Gaming Plus
Storage: 1TB M.2 and a 500gb sata.
AIO: Corsair iCUE H100i PRO XT
Ram: CORSAIR VENGEANCE RGB PRO 32GB (4x8GB) DDR4 3600 C18
PSU: EVGA 750 GQ Gold
CPU: Ryzen 7 5800x
GPU: RTX 3080TI MSI Ventus

Im just looking for a rough price so I can figure out how much it's worth.

Then I can get it listed somewhere. I don't even know where to begin. Maybe ebay?

Thanks
