My current system has a side window but nearly no RGB. I didn't use any RGB fans since I didn't want the lighting and would hate to do the cable management for them. Also no RGB on the RAM and the motherboard has RGB disabled. That leaves the white Nvidia logo on the GPU. I can disable that with a third party app, but have actually considered disassembling it to unplug the cable for the RGB.. It's the only thing lighting up the inside of my PC and I wouldn't mind to have it all in darkness. Don't mind the subdued red on my keyboard and mouse nor the red backlighting of the monitor, which is basically all the RGB present in my system.
