I done a bit of my own research on the Antec 900 and the Zero.
It seems that although the Zero is bigger and has millions of fans, its airflow does not compete with the Antecs.
I thought this would be the case as the antec sucks air through 2 120mm in bottom front ans pushes it out through a 120 and a 200mm at the top/back.
I can also ass another 120 in the middle to move air quicker and one on the side to cool the graphics card.
I think i will stay with the Abtec Nine Hundred
Has anyone had issues with the Thermaltake toughpower PSU's in this case?
