In front of the main hard disk drive cage there is a 120-mm fan. This fan uses a 4-pin connector, being installed to the ESA module, allowing you to monitor and configure the fan speed thru nVidia ESA software.

The two bottom hard disk drive modules can be removed for the installation of additional 120- or 140-mm fans – if you are not using these modules, of course. Their removal is done by unscrewing the thumbscrews present on the bottom panel of the case.

On Figure 23 you can see the adaptor for installing a floppy disk drive or an eighth hard disk drive to the case.

The installation of 5 ¼” units is really simple. With the front doors opened, remove the cover present on the 5 ¼” bay you want to use, slide the 5 ¼” unit until you hear a click and that’s it! It couldn’t be easier. If you think your device isn’t firmly attached to the case, you can use regular screws to fasten it to Armor+.
