In Win Development Inc., a leading innovator and multi-winner of the internationally renowned red-dot Design Award, has today announced its next generation ATX PC chassis, the 303C.

Building on the popular 303 chassis, the 303C adds USB 3.1 Gen 2 (10Gbps) Type-C to the front I/O, bringing the fastest external connectivity within easy reach. This new connectivity standard is compatible with many of the latest motherboards, including:

MSI: Z270 MPOWER GAMING TITANIUM, Z270 GAMING M7, X370 XPOWER GAMING TITANIUM:

MSI Statement: “We are excited to see our partner In Win releasing new chassis that use the new USB 3.1 Gen 2 Type-C connector. This new Type-C connector is supported on several recently released MSI Z270 and X370 GAMING motherboards, enabling gamers to enjoy full speed USB 3.1 Gen 2 transfer rates.”

ASUS ROG: MAXIMUS IX EXTREME, MAXIMUS IX FORMULA, MAXIMUS IX CORE, MAXIMUS IX HERO, CROSSHAIR VI HERO

ASUS ROG STRIX: Z270E, Z270G and Z270I

GIGABYTE: Z270X-DESIGNARE

Future motherboards will also include the new internal connector.

In addition to the new front panel connector, there is new support for respective RGB lighting systems, including: ASUS RGB AURA Sync, MSI RGB Mystic Light Sync and Gigabyte RGB Fusion. These RGB systems use 4-pin connectors to connect to the 303C’s built-in lighting elements. This enables users to sync their internal lighting choice to the case’s external lighting. The chassis includes an extra 4-pin RGB port allowing customers to ‘daisy-chain’ on an additional RGB device, such as LED strip or fan. (Note: Gigabyte uses a 5-pin connector that will not fit on the 303C’s connector. The extra pin is for white light, but the RGB feature will still function.)

The 303C presents an affordable chassis with premium materials, such as a 3mm tempered glass side panel, 1.2mm SECC steel and a distinctly clean front panel.

In Win constantly sets the standard for innovative PC chassis and the 303C is no exception. It features a detachable tempered glass side panel with a quick release button, tool-less removable dust filters and extensive cooling options including up to 3 x 120mm fan (360mm water cooling radiator compatible) at the top, 1x 120mm fan in the rear and 3 x 120mm fans at the base. Heatsinks can fit up to an ample 160mm tall. Overall, this creates a bottom to top airflow that complements natural convection.

Another unique design can be found in its top PSU chamber (up to 200mm), 2.5” SSD (x2) and 3.5” HDD (x2) that sits above and behind the motherboard. Not overlooking any detail, a specialized graphics card holder is provided to discretely support  longer cards.

The 303C is available in black or white, supports E-ATX, ATX, micro-ATX or mini-ITX motherboards, has space for up to seven PCI slots and 350mm long expansion cards. The front I/O includes USB 3.0 (x2), USB 3.1 Type-C (x1) and 3.5mm stereo HD audio jacks.

In Win plans to launch remastered versions of past models with similar features such as: 301C, 509C and 101C. In Win will continue to do its part in providing innovative products to the PC building community.
