Investigate

Audit the build before it leaves the bench

A supplier submits a $900 PC for a technical trainer, citing a successful boot as acceptance. Audit the full quote, CPU firmware support, calls, concurrent apps, projector output, and recovery evidence before authorizing handoff.

Decision 1

Recalculate the actual budget

The component subtotal is $910 and includes a removable $35 cosmetic panel. Required cooling costs $40 and shipping $25 were omitted. The total setup limit is $900.

Key ideas

  • A PC design is a set of compatibility and support promises.
  • Requirements come before recommendations.
  • A compatibility matrix catches cross-part conflicts before purchase.
  • Balanced builds spend on real constraints while protecting stability.
  • Validation proves the system meets the user brief.

Check your understanding

  • Can you turn a vague user request into requirements?
  • Can you check CPU, board, memory, GPU, storage, PSU, and case together?
  • Can you explain a tradeoff in budget, heat, power, or serviceability?
  • Can you validate a build against the named workload?
