Interesting case. Other than the shear size and weight, the size of which might be a reason not to buy, it's a very tempting build option. I just bought the Phanteks Enthoo Evolv X, which has a lot of similar options. The Phanteks still weighs 43lbs vs this at 53, so both are heavy. Be neat to take my same build and put it in this case to see what temps I could get for the same price. Seems like you would get better airflow with the Tower 900. Kind of surprised you can't put two systems in it, like you can with the Evolv X...considering how much space is there. I'm curious what it's like to build in this system.
