You can find one in almost ANY used computer that you buy at a swap meet, Craig's list, or even refurbished. Don't count on someone wiping the HDD in the computer. If a used PC that I bought had a HDD, I'd look at it. If it was from a compny, I'd look at it a lot harder and I'm not a criminal. Here's an example. At work, I had to send over 800,000 social security numbers to the four main cell network companies for analysis as to what information they could provide on every one of them (yes, legal, but that isn't the point). one company said "just attach the list to an email". Do you think that would be secure? If you knew how the Internet works, the answer would be "no way". But each of the other companies had their own requirements. At the time, one-way encryption was used on the SSNs and then the entire file was encrypted with 4096-bit encryption and a pass phrse of over 154 characters including spaces, special characters, upper case, lower case..... Was it 100%? No. But the question was: was this "over-kill"? Not if those SSNs could be hacked and criminally used.
The point being that we don't know what the OP is asking about. Is it a regular PC that never did online banking? Or is it for a company that has governed data like credit card transactions or medical records? We don't know. So, we don't know the true meaning of what you said in the term, "less likely". If this one HDD had banking information on a few thousand people, it could be worth it to use whatever extraoadinary means to determine what the data is because it could be worth millions of dollars. We just don't know the scope of what we are talking about and where you draw the line in the item; "of note".
