What Is a Box Build?

A box build (also known as system integration) is the process of assembling all electronic and mechanical components into a finished enclosure. Instead of sourcing and assembling these pieces separately, Southrock Engineering delivers a turnkey solution that’s fully assembled, tested, and ready for use. This includes:

Printed circuit boards (PCBAs)

Internal wiring and cable harnesses

Power supplies and distribution

User interface components (switches, displays, connectors)

External I/O connections

Enclosures, housings, and mounting hardware

Turnkey Box Build Solutions

Complete Enclosure Systems

We integrate PCB assemblies, power components, and interface elements into a single, cohesive unit. Every build is customized to your specifications, ensuring proper fit, thermal management, and long-term reliability. These systems are commonly used in:

  • Industrial machinery
  • Control panels
  • Medical and safety devices
  • Monitoring and automation systems

I never thought of that!

That’s the phrase we hear most from new customers. Southrock is a partner that solves the problem, not just sells a service. Our end-to-end capability reduces delays, simplifies logistics, and ensures accountability throughout the entire build process.
