Power Supplies and Case Assembly
Lesson 1 • Full System Assembly and Cable Routing
Integrates all previously installed components into the case with complete cabling. Students verify power delivery and achieve a clean, maintainable build.
Lesson 2 • Case Selection and Component Placement
Evaluates case size, airflow design, and drive bay availability against build requirements. Strategic component placement reduces thermal and cable management problems.
Lesson 3 • Power Supply Unit Fundamentals
Covers wattage calculation, efficiency ratings, and rail configurations for modern systems. Correct PSU selection prevents instability and component damage under load.
Lesson 4 • PSU Connectors and Cable Management
Identifies every PSU connector type and maps each to its target component. Organized cabling improves airflow and simplifies future maintenance.
Chapter 4HideHide detailsSee detailsStorage Devices: Selection and Installation
Storage Devices: Selection and Installation
Lesson 1 • Storage Technology Overview
Compares HDD, SATA SSD, NVMe SSD, and optane storage on speed, cost, and use case. Selecting the right media type is foundational to system performance planning.
Lesson 2 • RAID Concepts and Configuration
Introduces RAID 0, 1, 5, and 10 for redundancy and performance, and explains hardware vs. software RAID. Students configure a basic RAID array in firmware.
Lesson 3 • Physical Installation of Storage Drives
Covers mounting HDDs in drive bays, seating M.2 modules, and connecting SATA cables. Proper physical installation prevents vibration damage and signal errors.
Lesson 4 • Partitioning and File System Basics
Explains MBR vs. GPT partition schemes and common file systems such as NTFS and exFAT. Students partition and format a drive in preparation for OS installation.
Chapter 5HideHide detailsSee detailsGraphics, Expansion Cards, and Peripherals
Graphics, Expansion Cards, and Peripherals
Lesson 1 • GPU Architecture and Selection
Explains VRAM, shader cores, TDP, and slot bandwidth for GPU selection decisions. Matching GPU to PSU and case clearance prevents installation failures.
Lesson 2 • Other Expansion Cards
Covers installation of sound cards, capture cards, and wired network adapters in PCIe slots. Students configure each card through device manager and verify functionality.
Lesson 3 • Installing and Configuring the GPU
Covers PCIe slot seating, bracket removal, power connection, and driver installation. Correct GPU setup is required before display output and benchmarking tasks.
Lesson 4 • Peripheral Connection and Configuration
Connects monitors, keyboards, mice, and USB hubs, then configures display and input settings. Peripheral setup completes the workstation for end-user operation.
Chapter 6HideHide detailsSee detailsOperating System Installation and Configuration
Operating System Installation and Configuration
Lesson 1 • System Updates and Security Baseline
Applies OS updates, configures firewall settings, and establishes a security baseline. An updated, secured OS is the minimum standard before user data is introduced.
