Gigabyte mobo I choose because I'm love the brand and never had any issues with any board in the past. It is RGB one also and I had z170 gaming 7 before that and in really liked that one and that's the only reason I went with it. Color tubbing I chose because I didn't want to add any dye into the tank due to ekwb issues with dye leak okkng between the base and acrylic top. Making spiderweb thruout the block.
Since I didn't want to run into those issues I picked the color tubes and color coolant vs clear coolant and dyes
That looks awesome :)
Mouse is sick
Since you can add weights to it and make it perfect weight. That's what makes it awesome. Rgb lights on it are great too and feel is just right .
And yeah white pastel would look awesome :)
