Yep I know what you mean the HAF came with a red LED 200 at the front and two no colours 200's at the top so they are all blue LED and so are the two 140's in the side panel.
The Intel LC is also lit up blue and I have just fixed a new blue LED HDD light in the the front of the top case cover / switch USB box. It was red along with the power on switch but as I don't see that now I have left it red.
I was thinking of running some blue LED strips around inside the case but my mate said it wouldn't show up too well so have dropped that idea. The case originally came with the clear panel that I did not want and sent it back but in hindsight should have kept it
Nevr mind it has turned out quite well anyway.
