Antec 900 VS ThermalTake Armor +MX

Hey!

I Just bought my new PC, and I had a slight problem picking up a good case

At first, i wanted to take the Armor +MX with Ultra 120 Extreme
The store told me it doesn't have enough room, so I told them to try with the Tuniq Tower

They said it can be fit in, but then no room to work in the case
I could have take the case with Freezer 7, but didn't want to

So I choose the Antec 900 case with Ultra 120 Extreme

Is that a good choice? heard the A900 have dust issues and noise problem, but overall it great case
