I while back I was thinking about the same thing. I hadn't seen this video beforehand but I made the same decision to go w/ the Luxe, one the the big reasons being the included Phanteks Hub does exactly what you want. Of course, Dimitri has a few more reasons.

The Phanteks Hub can use either PWM or DCV MoBo header output to control fans.
-With DCV header, it can control up to (6) case fans per header
-With PWMheader, it can control up to (11) case fans per header
On our Primo build...I use 3 of those hubs:
1st controls (6) fans on 140 x 420 radiator
2nd controls (4) fans on 140 x 280 radiator
3rd controls (6) case fans
