As a leading brand in the computer chassis, thermal solution, and power supply unit. Thermaltake has released the Urban S31 mainstream mid-tower, one of the members of Thermaltake's newest chassis series – Urban Series. The entire series has a sophisticated and cutting-edge look. With classic edition and windowed edition, Urban S31 is designed for users who look for powerful performance and high expandability but with a more simple and sophisticated look. Urban S31 is built with brushed aluminum finish and steel mesh front door panel to mask the extrusive drives and devices ( 3 ODD and 6 HDD drive bays), not only to unify the appearance, but also provide a simple yet elegant aesthetic appeal; the sophisticated look also can be used to match other sleek designs found in your home theatre installation. Easy Installation The perforated front-top panel has implemented two of latest data transfer devices with SuperSpeed USB 3.0 ports along with two USB 2.0 ports, a HD microphone and headset jack, to grant direct access when needed. A top-mounted 2.5" or 3.5"HDD Docking Station enables blazing fast file transfers and effortless hot-swap drive replacement for easy setup or removal of storage or backup media. Advanced Ventilation & Innovation There are two preinstalled 120mm fans to optimize system ventilation in the Urban S31. Plus pre-mounted holes for more ventilation options, allowing users to build up system ventilation to their preference. The latest tool-less innovation with 5.25" & 3.5" tool-free drive bay design minimizes the hassles of installing ODD, HDD and other bay mount devices. Maximize Expandability Pre-installed holes enable users to support motherboards up to standard ATX and a rear CPU cutout in the motherboard tray to assist with cooler installation and even extra space for extra-long graphics cards as well. Rubber grommeted holes are included to ensure cables can be tucked away for effortless cable management along with liquid cooling tube routing. More cases are going to be introduced in the Urban Series. Same family, yet different performance and features to suit user's need.
