Frequently Asked Questions (FAQs)
What is the main advantage of a micro ATX case?
The primary advantage of a micro ATX case is its balance of size and functionality. It’s smaller than a standard mid-tower ATX case, saving desk space, but still large enough to accommodate powerful components like large GPUs and multiple cooling fans, offering more flexibility than a smaller mini-ITX case.
What is a dual-chamber case design?
A dual-chamber design, like the one in the NZXT H6 Flow, separates the main heat-producing components (CPU, GPU) from the power supply and storage drives. This helps to improve airflow and thermal performance by preventing the heat from the PSU from affecting the main components.
Do I need to buy extra fans for these cases?
Not always. Cases like the MUSETEX and LIAN LI O11D come with a full set of pre-installed fans, providing excellent cooling right out of the box. For other cases, while they may include some fans, you might choose to add more to maximize airflow depending on the intensity of your build.
Can I fit a large graphics card in a micro ATX case?
Yes, most modern micro ATX cases are designed to support large, high-end graphics cards. All the cases on this list, such as the MUSETEX which supports GPUs up to 420 mm, have generous clearance, but it’s always important to check the specific dimensions before you buy.
What is a pillar-less design?
A pillar-less design, seen in the LIAN LI O11D and NZXT H6 Flow, uses two adjoining tempered glass panels (front and side) that meet at the corner without a metal frame or pillar obstructing the view. This creates a seamless, panoramic showcase of your PC’s internal components.
