We covered Rockchip RK3399K processor a few months ago, as a version of RK3399 processor qualified to run at 2.0 GHz, or supporting a wider-temperature range (-20 to +85°C) at 1.8 GHz.
We found out about the new processor, as Kobol was working on a Helios64 SBC designed for NAS that featured RK3399K SoC. At the time, we just had a drawing of the board and some specifications, but now the company has announced pre-orders for the board and a complete 5-bay NAS kit will start next week and the actual shipping start in March.

Kobol Helios64 5-Bay NAS Enclosure
Kobol’s first product, Helios4 NAS SBC, would optionally ship with an acrylic enclosure which kept cost low, but it was not necessarily the most eye-pleasing design.

So the company has come up with a much nicer design for Kobol Helios64 enclosure as shown above.
Key features:
- Support for up to 5x 3.5” SATA HDD
- Hot-Plug HDD Tray System
- Integrated Control Panel
- 1x USB 3.0 Port
- 2x 80mm PWM Fans
- Dimensions – H 134mm x W 222mm x D 250mm
All necessary cables as included with the case.
The company also plans to offer an adapter kit to install Helios64 SBC in any mini-ITX tower to recycle old PC cases.
