OH MY GOD, I got my white Define R4 today, and I CANNOT get over how amazing this case is!!! I truly had worries about the cooling capabilities, but it's simply incredible how well it suits my system while providing excellent sound insulation.
I took a lot of photos, because when I was looking into buying this case, there was a very limited number of user images of the white case version. And I had questions, like how glossy is the front panel, what is the case paint texture like? etc. So here are photos and the info on my build.
Empty case:


Powdercoated paint texture:


The case is very glossy, and the front panel is not tacky at all. I was going to get brushed aluminum or wood-textured 3M vinyl and paint the case some other color, but I have now reconsidered and will be keeping it as is! (and I love modding stuff)
Front panel gloss / reflectivity:

Corsair H100i in push/pull configuration with Scythe Gentle Typhoons (120mm) fans, attached to the front panel (I snipped off the plastic grille, as it was meant for 140mm fans and is unnecessary anyway):

H100i installed at the front (tiny motherboard! moving from my Prodigy build)

Intake front the front (H100i) + bottom fan. Bottom fan air and front going up to the reference graphics card fan and getting exhausted out of the case through the GPU shroud. Rear fan in exhaust mode. Top vents closed completely.

2 case fans (Phanteks 140mm and a Scythe Gentle Typhoon at the bottom) at 5V controlled by the case controller. 4 Scythe Gentle Typhoon fans on H100i in push/pull at static 800RPM (4.3GHz i7 3770). CPU stays under 45C while gaming, GPU stays at 70C. Stock reference GPU fan is buzzy, but I can BARELY hear it in this case!!! I am truly amazed.

Case closed and under my desk (Eventually going to put in IKEA Dioder lights inside to illuminate the window, but far too exhausted for tonight!)
