Going off one listing for a E5-2697v4, $50 with free shipping, 386 already sold.
If you figure after the double-dipping of eBay/Paypal and then shipping fees, that's ~$30 profit per CPU.
8024 x 30 = 241,920 USD. Not too shabby for what's got to be some weeks/months of work. You could probably assume that they can sell or scrap the rest of it for a bit more as well, minus the fees for storage and moving company.
