Under the label "Jonsbo - powered by Cooltek" we present the highest quality cases for demanding users.

The RM1 is an elegant ATX Mini-Tower that offers a timeless design line with rounded corners and a very appealing exterior.  The RM1 uses brushed aluminum and shines with its superb quality. The unobtrusive design of the case ensures that it can blend in with any interior style.

The front panel offers an external 5.25 drive bay for the installation of an optical drive. Power- and Reset-Button, 2 x USB 3.0 as well as HD audio ports are located in the lower left part of the front. Chassis and side panels of the RM1 are made of 1.8 mm strong, anodized aluminum. Two color options - black and silver - are available.

Based on our experience and by studying customer requirements, the focus during the development of the case series was the idea to offer the user the best possible variability for the installation of hardware:

Despite the very compact dimensions of the RM1, the intelligent interior design allows the installation of motherboards of up to 305 x 245 mm. This means, full-size ATX boards can be installed, as can Micro-ATX or Mini-ITX systems. The RM1 can accommodate standard ATX power supply and offers a total of 6 expansion slots.

Please keep in mind that if you install an ATX board, the external drive bay cannot be used anymore. In order to exploit all the features of the RM1, we recommend using Micro-ATX motherboards.

The high-quality and well-manufactured Mini-Tower can accommodate VGA-cards with a maximum length of 290 mm and CPU-coolers with a maximum height of 95 mm.

The RM1 can be equipped with one 2.5 inch and one 3.5 inch hard disk. The HDD are secured with rubber-suspended screws at the bottom of the case. In addition, two 2.5 inch SSD can be mounted on the ODD frame, if no optical drive is installed.

For ensure effective case ventilation, the RM1 is equipped with an included quiet running 120 mm fan behind the front. The performance of the fan can be adjusted individually to your own liking via an external multi-stage switch. The right side panel offers air holes in the front, in order to allow for a continuous air exchange.

The RM1 is aimed at users who are looking for a very stylish, full-fledged PC for typical living room applications or gaming. The stylish case rests on vibration-decoupled case feet in the appealing looks of high-quality Hifi components.

Depicted hardware is not included.
