Tough call to make.
The Thermaltake has six more bays total and one more fan total.
On the other hand, it's larger and heavier.
The Gigabyte looks like it should have better airflow, and all three of its fans are 120mm.
I really don't see myself using even the number of bays the Gigabyte has, but the Thermaltake is only $5 more. I guess the issues to ponder are weight, airflow, and fans.
How do you weigh in on this, Particle? The Thermaltake looks like a better value, but the weight and air issues might counteract that. I think the matter is really more subjective than anything, so feel free to leave this to me unless there's something I need to know.
