Just curious as to where does all of the hardware go that you no longer use or test? Do you sell it on eBay, Facebook, donate, etc. I am just curious and interested if you do sell them. Thanks in advance.
I zero out boot drive and any data drives, clean out the dust, install Windows 10 and donate to Goodwill. My departing machines are very used but is strong enough for browsing and basic tasks. Some kid with $50 can get a working system for internet and homework.
If non-working, I wait until I have several of them and then truck down to the electronics recycling at my local transfer station. I spike the drives.
