Those look like 12v RGB connectors however is it just me or does one of those 3 connectors look to be with one missing pin...? If so, that one is an ARGB connector. Do you have RGB/ARGB devices to work with in your build? The case you've mentioned doesn't come with RGB/ARGB fans(last I checked, could be wrong on that one). The motherboard you own is the base model which lacks the RGB header located at the bottom of the motherboard, towards the front panel audio. It also lacks the ARGB header at the top of your motherboard. The soldered points are there just that the pins are missing. No soldering on pins, will void the warranty on your motherboard so that is not an option.
You might want to swap that board out for one with ARGB or RGB headers(or maybe look into an add-on ARGB/RGB controller) if you want to get the illumination at the bottom of the front fascia of the case.
