The case reviews so far have only mentioned the LED colours...which is not the critical part. It's the brightness that matters the most - after all, what use are "indicators" you can hardly look at??? They should also be diffused as a matter of course. The LEDs on the In Win Z583 for example do look to be very bright in the photo.
As a matter of curiosity, I've added a poll on the colours, so you can decide which of them you prefer.
