So I am working on this custom build for a customer and the power supply and hard drive need to be replaced. But holy crap does this thing have a huge heat sink, and it is right in the way of removing the power supply. Normally removing heat sinks isn't an issue but this one seems to be really stubborn and I'm not certain I am trying to unscrew the right screws? Just wanted to get some people's opinions and ideas to help remove this sucker. Pictures included~
