Where do you sell your used tech?

I tried to offload a new dual socket motherboard on eBay that I’ve been hoarding in a closet for two years. I was confronted with new requests for my SSN and reminders my funds would be held for an indeterminate amount of time, which quickly reminded me why I stopped using this platform to begin with.

Where do you guys sell technology you don’t want anymore but may still have some value?
