[SOLVED] cooler master q300l

[jacob006]

Does anyone know what the LED means on the front I/O panel of the cooler master q300l case? It has a symbol right next to it that looks like 4 discs stacked on one on the other. It blinks randomly but usually stays off.

Sounds like hard disk activity led to me, not that many cases have them nowadays
