The C3 Plus is an evolution of the hugely popular C3. Jonsbo has taken an outstanding product and made some detailed improvements - the C3 Plus is ideal as a media server and is aimed at price-conscious users who do not want to compromise on quality.

Changes in manufacturing have given the C3 Plus superior stability. The C3 Plus combines a high-grade exterior made of 1.5 mm thick aluminum with an extremely stable interior made of 0.8 mm thick SECC steel. To show off your build, the C3 Plus is equipped with a full-surface window side panel made of tempered glass.

When looking at the interior, the first thing you notice is the power supply cover, and the C3 Plus also has the option of hiding the cables behind the motherboard tray. The C3 Plus is equipped with a 140 mm case fan in the lid and there are a number of additional air holes on the front right side of the housing to improve the supply of fresh air.

The intentionally simple design of the C3 Plus blends perfectly with any environment. The I/O panel with power button and 2 x USB 3.0 is inconspicuously integrated on the front left side of the front. Two color options - black and silver - are available.

This high-quality, well-engineered Micro-ATX chassis supports motherboards up to a maximum size of 245 x 245 mm. The C3 Plus offers space for standard ATX power supplies and has a total of 4 expansion slots. The tidy interior of the C3 Plus can be equipped with long VGA cards up to 280 (340) mm in length. CPU coolers up to a mounting height of 170 mm can also be accommodated in the C3 Plus.

The C3 can be equipped with a 2.5-inch SSD and four 3.5-inch HDD or three 2.5-inch HDD / SSD and three 3.5-inch drives. Behind the front is a specially designed mounting frame for two 3.5 inch drives. This can be removed for easy installation of the drive after loosening a few screws. You can choose to install two 2.5 "or 3.5" drives at the top of the power supply cover. At the bottom of the case there is a mounting space for a 3.5 inch HDD. Finally, a 2.5-inch SSD can be mounted behind the motherboard tray.

The ventilation system of the C3 Plus offers a variety of mounting locations for fans to ensure outstanding ventilation. A quiet running 140 mm fan is already preinstalled under the housing cover. A 120 mm fan can be mounted on the rear of the housing and another 120 mm model can be installed on the power supply cover inside the case. Finally, instead of the two 3.5-inch drives behind the front, two 120 mm fans to improve the fresh air supply can be mounted. There is 35 mm of space between the front and the frame, which makes it possible to install the fans or even the radiator of a compact water cooling system here.

The C3 Plus is aimed at users who are looking for a particularly attractive PC for typical living room applications or even a sophisticated gaming system. The housing perches on vibration-decoupled housing feet in the appealing look of high-quality hi-fi components. Externally, the user has two USB 3.0 "Super Speed" ports available. Thus, external drives or USB sticks can be connected quickly and easily.
