Guys, the front cover snaps off easily. From below, pull towards you and voila, install the front fans. And then many simply cannot open the instructions, everything is written there. And yet, on the front you have two choices: three 120mm fans, or two 140mm fans. I set 2 to 140, because if you set three, then the bottom fan blows into the HDD bay, I see little sense from this.
The photos I added should give you a good idea of what to expect from this experience.
