The entire series has a simple and elegant aesthetic look; designed for users who looks for powerful performance and high expandability but a flamboyantly appearance or more simple and sophisticated look. Urban S21 built with metal brushed front door panel to mask the extrusive drive devices ( 3 ODD and 6 HDD drive bays), not only unify the appearance, but also provide a simple yet elegant aesthetic; the sophisticated look can also be part of decoration at home to enhance living quality. The Front-top panel has implemented two of latest data transfer SuperSpeed USB 3.0, a HD microphone and headset jacks, to grand direct access when needed, and a side window opening panel to take an instant glance of the interior. Advanced Ventilation & Innovation There are two preinstalled 120mm fans to optimize system ventilation in Urban S21. Plus pre-mounted hole for more ventilation options, users still can build up system ventilation by their preference. The latest tool-less innovation with 5.25" & 3.5" tool-free drive bay design minimized the hassles of installing ODD and HDD devices. Maximize Expandability Pre-mounting holes enable user to support motherboards up to standard ATX and CPU cooler installation, the extra long graphic card as well as rubber grommet holes for Advanced Cable Management and Liquid Cooling System. There will be more cases introduced in March along with Urban Series, same family, yet different performances to suit user's need. For more information, visit the product page.
