Motherboard Compatibility

Correct Answer: Memory slots

To ensure compatibility between the motherboard and DDR4 RAM, Sara should check the memory slots on the motherboard. The memory slots must match the type of RAM being used. Checking the CPU socket is incorrect because it determines CPU compatibility, not RAM compatibility. The power supply connector is unrelated to RAM compatibility. PCIe slots are for expansion cards and also do not determine RAM compatibility. Therefore, the memory slots are the key factor to check for ensuring the DDR4 RAM will work with the Mini-ITX motherboard.

Correct Answer: M.2 slot

The best connection for a high-speed NVMe SSD is an M.2 slot on the motherboard. M.2 is a form factor specifically designed for SSDs, providing high-speed PCIe lanes for optimal performance. PCIe x16 slots are primarily used for graphics cards and would be overkill for an SSD. SATA ports are too slow to take full advantage of NVMe speeds, as they are limited by the SATA interface. USB 3.1, while fast, is still slower than a direct M.2 connection and would require an external enclosure, which is less efficient than connecting the SSD directly to the motherboard.

Correct Answer: Purchase a new PC case that supports ATX motherboards

The best solution is to purchase a new PC case that supports ATX motherboards. An ATX motherboard is larger in size than mATX and Mini-ITX motherboards, and will not fit in a case designed for the smaller form factors. Trying to force the ATX motherboard into a smaller case or modifying the existing case by cutting it could damage the motherboard and other components. Removing components to make space is also not a viable solution as the case dimensions would still not accommodate the larger ATX board. Therefore, getting a new case built for ATX motherboards is necessary to ensure proper fit and function of the system.
