how to install Thermaltake S300 Tempered Glass Mid-Tower Chassis

• Begin with a clean workspace and ensure all packaging materials are set aside. Remove the side panel and any internal accessories to access the chassis interior. Verify that you have all the mounting screws and standoffs needed for your motherboard and drive configurations before starting.
• Install the motherboard standoffs in the correct locations for your ATX, Micro-ATX, or Mini-ITX board. Align the I/O shield, then secure the motherboard using the appropriate screws. This step establishes the backbone of your build and sets the stage for clean cable routing.
• Prepare the power supply (PSU) and install it into the PSU bay. Route the main power cables toward the motherboard area through the back of the case, ensuring that you leave ample slack for cable management. Attach the PSU screws securely to keep the unit firmly in place.
• Mount your componentry—graphics card, memory, and cooling system—using the provided expansion slots and mounting points. If you’re installing a 120/140mm radiator or an AIO cooler, position it in the front or top mounting locations according to your thermal strategy, then secure with the respective screws.
• Install storage drives in their designated bays or trays. Use the included mounting hardware to secure 3.5" and 2.5" drives, ensuring that cables are routed away from fans and airflow paths to prevent interference. Connect power and data cables to each drive and route them neatly behind the motherboard tray.
• Route all cables behind the motherboard tray using the built-in channels and tie-down points. Attach the side panel, ensuring the tempered glass aligns correctly with the window opening. Double-check all connections, then power on to verify the system posts and the cooling configuration performs as intended.
