How to install Thermaltake Tower 300 Bumblebee Micro Tower Chassis

• Step 1 — Prepare your workspace and gather components: anti-static measures in place, screws and standoffs ready, and a clear plan for your radiator, fans, motherboard, and GPU layout. Remove the side panels from the Tower 300 Bumblebee to access the interior and study the mounting points before you begin.
• Step 2 — Install the power supply and secure it: slide in the power supply unit (PSU) into its designated area if the chassis supports bottom mounting, then secure it with the included screws. Route the main power cables through the appropriate cutouts to keep cables tidy and unobtrusive.
• Step 3 — Mount the motherboard: install the motherboard standoffs in the micro-ATX tray, align the I/O shield with the motherboard, and carefully secure the board with screws. With the motherboard in place, attach memory modules, CPU cooler or AIO block, and any other peripherals you plan to use so you can verify clearance and fit as you proceed.
• Step 4 — Install cooling components: if you’re using a right-side 420mm radiator, mount it with fans oriented to optimize airflow through the interior. Connect fans to headers or a fan hub, and route tubing if you’re building a custom loop. Ensure there is adequate clearance for tall CPU coolers and GPU length, adjusting mounts as needed to prevent contact with the chassis.
• Step 5 — Add storage and expandability: install any 2.5" or 3.5" drives in their respective bays, making sure cables are routed along the built-in channels to minimize obstruction to airflow. Plan GPU and PCIe expansion placement early to avoid conflicts with radiator hoses and cables.
• Step 6 — Manage cabling and finalize assembly: route power, fan, and data cables through the cable management features and behind the motherboard tray. Use zip ties or Velcro to secure cables, keeping airflow paths clear and the interior neat for optimal cooling performance.
• Step 7 — Attach side panels and optional stand: reattach the side panels securely, ensuring the tempered glass (if present on your configuration) is properly seated without stress. If you own the optional Chassis Stand Kit, install the stand per its instructions to elevate the chassis and achieve the stand-out display look while preserving easy access to ports and components.
