Evaluating the Worth of My Almost Five-Year-Old Gaming PC

As I consider parting ways with my nearly five-year-old gaming rig, I’m curious about its current market value. Here are the specifications of my setup:

Case: be quiet! Pure Base 500DX
Processor: Intel Core i7-10700K
CPU Cooler: be quiet! Dark Rock 4 Pro
Motherboard: ASUS ROG Strix Z490-E Gaming Mainboard
Graphics Card: ASUS GeForce RTX 3080 ROG Strix O10G
Storage: 2TB Samsung 970 Evo Plus M.2 2280 PCIe
Memory: 32GB Corsair Vengeance LPX DDR4-3200 (2x 16GB)
Power Supply: be quiet! Straight Power 11 850W ATX
Additional Features: Upgraded fans to be quiet! Silent Wings 3

With this configuration, I imagine it can still deliver excellent performance for gaming and other demanding tasks. I would appreciate any insights or opinions regarding how much I might be able to sell it for in the current market. Thank you for your input!
