First LEGO PC, the Model Grond Black Edition

GROND PC / Black Edition

Grond PC Black Edition was a huge challenge for us. It is a premium computer that combined the uniqueness of the case with the latest technologies. Grond PC has been designed for advanced and demanding users. Adequate performance for gaming, 3D design, FEM analysis, in original Lego housing. Used every day in the Multi – split system, it helps the family work from home and provides entertainment in the highest 4K resolution.

Gaming hardware

Unlimited power in 1500+ LEGO bricks

Grond PC (black edition) was built from over 1500 Lego bricks . We distanced ourselves from the building of standard computers to embrace custom-built ones that have a modern housing and a very unique touch. The unique design allows the housing to be adapted to the needs of the customer and enables the configuration of the selected hardware. The fascinating form combined with the most modern components available on the market, stimulates the imagination and creates a huge range of possibilities when designing Lego Computers.

Water cooling system

To increase its potential and capabilities, we opted for water cooling, which will allow :

  • reducing the volume to 25 dB when the computer is turned on
  • reducing the CPU temperature to 34 ° C in normal mode (internet, watching movies, copying files etc.)
  • reducing the GPU temperature to 34 ° C in normal mode (internet, watching movies, copying files, etc.)
  • reducing the HDD temperature to 35 ° C
  • greater ability to overclock the CPU and GPU
  • automation of the Lego PC cooling process
Gaming hardware cooling

The system consists in cooling the following elements:

  • CPU
  • GPU
  • Second HDD
  • Automation controller

Additional items:

  • Reservoir
  • Flow meter
  • Radiator + 3 fans 140 mm
  • Pump
  • Couplings
  • Tubs
