Thermaltake has released a number of cases this month and has now added another model to that list with the Urban S31 mid-tower. The black steel case has two models, one with a side window and one without. Two 120mm fans are included, and up to four more can be installed to provide cooling options. The case has enough drive bays to hold three 5.25" drives and seven 3.5" drives, with an additional hard drive dock on top of the case. The Urban S31 can accommodate CPU coolers up to 155mm in height and GPUs up to 410mm in length when the hard drive cage is removed.
