Thanks for the advice, but I love RGB, yeah, yeah, I'm that bad, bad guy here.
Anyways, I think the Gigabyte looks amazing and as I was searching on google, they use the same Pump brand (Asetek) as other flagship AIO's as Corsair, NXZT, etc. So the only difference should be Fans and Design. And I think the design looks amazing and I'm willing to spend some more money on it, if needed. Also as I'll be changing the fans to match other Fans in case, I think Fractal Prisma is the best RGB Fan on the market right now, because they have the best static pressure and also RPM's, so they deliver fresh air to the radiator faster than others. But I don't know, I might be wrong, I'm just discussing things I somehow learned somewhere on the internet.
And btw I have Fractal R6 case with only pre-installed fans now. And also I think I somehow
