Question about Gigabyte B450 Aorus M

The mainboard has two connections each for any digital LED strips and analogue LED strips.
So you can install practically any LED strip.

(See here on page 14 for more details and page 4 to find out where to connect your strips: https://download.gigabyte.com/FileList...)

For a selection of LED-strips look here (also has single LEDs, couldn't narrow it down):

A possible choice would be this Play-Zone NeoPixel:
Play-Zone NeoPixel Digital RGB LED Strip 144 LED 1M White PCB

Have fun in the RGB world... :D
