Antec 900 or Thermaltake Armour

[Scooby_WR1]

Hi, i am looking for a case with decent cooling and plenty of space inside but can't decide out of the Antec 900 or the Thermaltake Armour Super Tower. I currently have a Thermaltake Tsunami Dream but it is too cramped inside and has poor cooling. I know the Armour is a lot bigger than the Antec but have heard that the Antec it is well designed inside.
You can sort of see how cramped it is
