Hi there, I can't make up my mind between this one and the Airflow version. The airflow comes with two black fans while the X comes with three argb of which the bottom one could be placed in the back, so it's a single purchase with lights.

The Airflow comes with the need to buy more fans separately, which levels up the price, and I wouldn't be spending extra cash on leds so it would be a black hole of a PC. So the only reason I can think of for not going for the 4000X is that the included fans might be crappy, although the Amazon reviews for them seem extremely positive.

Also, I can't figure out whether they're different cases altogether or if only the front panel changes. The Airflow reviews on Amazon contain a lot of mentions to thin cheap metal sheets while the X version is praised for the build quality so I'm confused about that too..

Edit: forgot to mention, silence is far more important than aesthetics for me, especially if it would be on overnight with me sleeping two meters away.
