[Level 20 Series]

Question 1:

I just ordered a Level 20 VT series case.  If I mount a 280mm AIO cooler on the top of the case, does it need to push air out or pull air in?  Does it matter which panel I use for the top for this AIO cooler?

Question 2:

Does the bottom 2 120mm fans push air out?

Question 3:

Any tips/mods I can do to enhance airflow as best as possible?

Question 4:

Any tips for hiding the cables as best as possible?

[How do I buy a single Riing Plus 14 Radiator Fan TT Premium Edition?]

For some odd reason I can only find a 3 pack for the Riing Plus 14 RGB Radiator Fan TT Premium Edition.  Do I have to order a 3pack and throw away the other 2?  How do I order just 1?

Also, if I want to synch it with a single Riing Plus 20 RGB Case Fan TT Premium Edition and also a Floe Riing RGB 280 TT Premium Edition AIO water cooler, can I use just 1 controller to control all of them or do I need a separate controller for the the AIO water cooling fans?
