Sharkoon Technologies is an international supplier of high-performance, high-quality PC components and peripherals, and in response to numerous customer requests, the manufacturer is now launching a white version of its REV300 Midi-ATX case. With the REV300 White, hardware builds take the proven approach of being installed around a 90-degree rotated mainboard, while the tempered-glass side panel is unconventionally placed on the right side of the PC case. In addition, the REV300 White comes with seven pre-installed PWM RGB fans.

Like its black counterpart, the white version of the REV300 comes readily equipped with the maximum possible number of fans: Apart from three addressable 140-millimeter RGB LED fans behind the front panel, there are also three equally addressable 120-millimeter RGB LED fans on the rear panel and another one under the top panel. To further maximize airflow, the front panel of the case consists of an air-permeable mesh. If water cooling is preferred instead of air cooling, an up to 360-millimeter radiator can be installed in the back of the case. There is also space for a radiator of up to 420 millimeters in the case's front - provided that the radiator does not exceed a height of 3.2 centimeters, a length of 46.5 centimeters, and a width of 14.1 centimeters.
 
Unusual but Proven Installation
All PC cases of the Sharkoon REV series are known for their unconventional configuration when it comes to installing the hardware build. The REV300 White is, of course, no exception here: The hardware components are installed around a mainboard that is rotated by 90 degrees with a result that is intended to provide a particularly stylish presentation through the tempered-glass side panel. And to open even more new possibilities in presenting the hardware, the glass side panel itself also breaks with convention and is to be found on the right side of the case, instead, as usual, on the left.

For Modern Components
Like the black version, the REV300 White should be an ideal case for large and modern components: Graphics cards with a length of up to 34.5 centimeters can be easily installed, as can CPU coolers up to 17.7 centimeters and power supply units with a maximum length of 27 centimeters. Near the front panel, on top of the case, a modern USB Type-C port ensures fast data transfer to mobile devices, while for everything else, the usual audio ports and four USB Type-A ports are also available.

Price and availability.
The Sharkoon REV300 White is now available at the manufacturer's suggested price of 159.90 euros.
 
The 90 degree rotation of the motherboard makes perfect sense to me. Heat rises so why not expel hot air from the top of the case.
