The 600T is a pretty sweet but it seems that it's not too popular among many people for some reason.
Because of it's price I assume. Airflow and water cooling potential is inferior to other cases in the same prices, which also have excellent cable management. I'm mainly referring to the Cooler Master HAF 932 (which is also a full tower case) and Silverstone Raven RV02. The CM Storm Sniper is cheaper, offers better airflow and many of the same features but has a smaller CPU backplate cut out and single HDD cage. It also has carrying handles. So the 600T needs to come down in price and maybe have some 120mm fans on the back of the HDD cage and it might be worth something.
