Design Rationale

  • The i7-12700K gave the customer a great amount of single-core and multi-core performance for regular CAD workloads. Heavier workloads would be tasked to the i9 builds.
  • Our default dual-tower air cooler was quite adequate for the i7, and it made the machine more reliable.
  • The customer wanted a stable motherboard with a good amount of desktop functionality.
  • The customer wanted at least 64GB of RAM.
  • The customer was fine with our default storage setup.
  • For maximum stability in their CAD workflow, a professional video card was recommended. As the heavier LIDAR workloads were being handled by i9+A4000 systems, an A2000 12GB was fine here.
  • The overall design of the build meant that a 850W Gold power supply was recommended.
  • We used our default mid-tower case to fit the Z690 motherboard
  • We used high-pressure fans to ensure proper cooling for the overall build.
