Matthew Soltys describes the steps taken to complete a custom computer build for a customer. He ordered the requested parts, installed the motherboard, CPU, CPU fan, RAM, and cover plate. He added standoffs and screwed the motherboard into the case. Matthew then plugged in power and front panel connectors and ensured good wire management for airflow and easy component access. Finally, he installed the CD-ROM, hard drive, video card, and operating system before adding drivers and Windows updates.
