How to install MSI Cubi 5 12M

• Plan your configuration: Decide which RAM capacity and type you will install, along with the storage drive (M.2 or 2.5" depending on the chassis). Since this is a barebone, you’ll save on components you already own while ensuring compatibility with your motherboard and power supply requirements. If you are new to DIY PC builds, start with a modest RAM size (for example 8GB or 16GB) and a fast SSD for an optimal balance of performance and price.
• Prepare your workspace: Power down and unplug all devices. Ground yourself to avoid static discharge. Gather your RAM sticks, SSD (M.2 or 2.5"), a small screwdriver, and a clean workspace to open and assemble the Cubi 5 12M safely.
• Open the chassis and access the internals: Remove the bottom cover per the manufacturer’s instructions. Locate the RAM slot(s) and the storage bay or M.2 slot. Be gentle with latches and connectors to avoid damage to delicate components.
• Install RAM and storage: Insert the RAM modules firmly into the DIMM slot(s) until they click into place. If your unit uses an M.2 slot, insert the NVMe SSD at a slight angle and secure it with a screw. If a 2.5" drive is supported, mount it in the designated bracket and connect it to the SATA data and power cables as required by the enclosure.
• Reassemble, connect, and boot: Reattach the bottom cover, connect a display, keyboard, mouse, and power, then boot the system. Enter the BIOS/UEFI to confirm detected RAM and storage, adjust boot priority if needed, and enable any required virtualization features or security settings recommended by MSI. Install your preferred operating system (Windows or Linux) and install the latest drivers and firmware from MSI’s support site or your OS provider.
• Finalize setup and optimize: Once your OS is installed, run updates, install essential productivity software, and configure network settings. For the best streaming and conferencing experience, ensure your drivers for WiFi 6 and Bluetooth are current, enable appropriate display scaling for 8K content, and configure your dual LAN setup if you plan to segment traffic for workloads or media sharing.
