I really enjoy the XS-PC model. That bracket makes it very simple to install on the back side between the GPU and the side panel in my 540. I'm curious about the glass tube inside, which has the XS-PC name on it.
There are two combos available. If, for some mysterious reason, you wish to proceed strictly EK, there is a pump accessories section. You can construct it yourself. I demonstrated the necessary components I recently purchased to achieve that.
