Earlier today a Sony Model DFI-D1000AA Development Kit for PlayStation 5 alongside a DFI-T1000AA PS5 Testing Kit surfaced on eBay receiving at least 12 bids totaling approximately $3,384.09 USD before the auction page was removed, however, iDCx1337 saved some images before the ad listed as a Sony PS5 PlayStation 5 Development Testing Kit 825GB DFI-D1000AA DEV/Test DevKit was pulled. 
Previously we've seen images of a DFI-D1000AA Development Kit for PlayStation 5 leaked online, a PS5 Development Kit Design Patent from Sony Interactive Entertainment with some unofficial 3D Renders followed by more PS5 DevKit Images leaked alongside a PS5 DevKit Cooling System Patent & Sony DFI-T1000AA Testing Kit for PlayStation 5 proceeded by the PS5 Software Development Kit leak with PS5 CP (Communication Processor) Box images.
According to iDCx1337 via DM on the removed eBay Listing Page images, to quote: "I knew it was going to get taken down so I saved all the pics that he had listed. By the angle of the images it's clear that it's from Sebo."
For those new in the PS5Scene he's referring to Robert Sebo (Elliot Alderson) on Facebook aka SCEDevNetwork on Twitter who was a Software QA Tester at PlayStation Europe, worked in Research & Development (R&D) at Sony Interactive Entertainment Europe (SIEE) and previously shared Screenshots and PS4 DevKit Tools in the PS4Scene among earlier dubious activities in the PS3Scene.
Check out the latest PS5 Development Kit (DFI-D1000AA) and PS5 Testing Kit (DFI-T1000AA) images from the now-removed eBay Page below, and should anyone spot additional PlayStation 5 development hardware (PS5 / Prospero equipment model number documentation by WillBettelheim) or software for sale publicly feel free to Contact Us or share it in the News Submissions forum section!
I hear there's some for sale over on tpr.scee.net
