|Regarding the ventilation
options you get with the ISK600 from Antec there is not much to say.
Basically fresh air is coming though the side Panels and the front and
at the rear there is an exhaust vent. There you actually see the only
fan you get with this case and it's a 120 millimeter model. As we mentioned earlier, removing the HDD
carriage allows you to install not only low profile coolers, but also
more powerful and larger down draft models. Since on the back there is a common 120mm slot, it is still possible to install a watercooling AIO solution with 120mm radiator.
