I just scrapped a lot of servers and found a lot of those copper heat sinks. Yes, you need to remove the screws or you will get #2 pricing for them.
Your yard may be different.
The fins, for lack of a better word, I thought were soldered on to the main block of copper but they aren't.
The whole heat sink has been milled from 1 piece of copper and will sell for #1 and hopefully bare bright.
You might even be able to sell them on ebay because they are just so dang purdy.
