Sharkoon has announced two new PC cases, the SK3 RGB and the TK4 RGB, featuring RGB lighting powered through the rear 120 mm fan or can offer four 120 mm RGB fans. These cases offer the same minimalistic design while featuring up to three SSDs and two drives to be stored in the HDD/SSD drive cage. Both of these cases are currently available, with the SK3 RGB having a price of €39.90 or roughly $47.74, while the TK4 RGB features a price of €49.99 or roughly $59.81.

The SK3 RGB and the TK4 RGB feature similar minimalistic designs, these case's design still offers a tempered glass side panel to ensure that PC builders can easily be shown off. This tempered glass side panel also allows the RGB lighting to be shown throughout the rest of your PC components easily. The rest of the case features a simple black design allowing these cases to be hidden away if all the RGB lighting is disabled.
