AOpen Dr. LED
That's what AOpen's LED product looks like. Dr. LED has no connectivity features like the products from Asus and Azza. It is an instrument for system monitoring. As you can see in the picture, there are LEDs for CPU, memory, AGP, PCI, floppy, the HDD, keyboard and a boot status LED.
Such a big case just for some LEDs would have been waste of space. AOpen included a CD box for 10 discs into the Dr. LED module (see photo). Just pull out the drawer to access the CD case.
