It typically measures 9.6 x 9.6 inches and fits into smaller cases without compromising too much on features. I found that these motherboards can support several components, making them ideal for budget builds or compact setups.

I measured my workspace to ensure that the case would fit comfortably on my desk. Additionally, I checked the height, width, and depth of potential cases to ensure they could accommodate my components without overcrowding. Cooling Options Cooling was another important factor in my decision-making process. I wanted to ensure that the case had adequate airflow to keep my components cool. I looked for cases that offered multiple fan mounts or the option for liquid cooling. I also kept an eye on the design of the case; some cases had mesh panels that allowed for better airflow, which I found appealing. Expansion Slots and Compatibility I quickly realized that the number of expansion slots available in the case was crucial for future upgrades. I considered how many graphics cards, sound cards, or additional storage devices I might want to install. Ensuring the case had enough PCIe slots and drive bays was essential for my long-term plans.

I looked for cases that offered features like cable routing holes, tie-down points, and ample space behind the motherboard tray. This would help me keep my build looking clean and organized, which I found to be quite satisfying. Price Range Budget was a significant factor for me when selecting a small computer case. I wanted to find a balance between affordability and quality. I researched various price points to determine what features I could expect for my budget. I noted that while some cases were more expensive, they often provided better cooling options or build quality.
