Where to buy cheap used computers?

Question

Iron

Ukraine. You need to get cheap Core i3 and higher computers, without video, except for the processor, nothing matters. That is, a general portrait - someone is selling a good office / home non-gaming piece of iron a couple of years old. The most savvy ones sell on bulletin boards, but the same savvy ones think that they bought 8 dollars and now they will sell for a "dollar" price and write some space figures. And there normal options are bought up quickly.
But there is a huge layer of people who sell the computer and at the same time do not send it to the announcement boards and forums. Which end up being sold at low prices.
Logic puzzle: where do such people live and how to find them?
