E-ATX vs Micro-ATX Case Specs
Motherboard support
The ASUS TUF Gaming GT501 supports E-ATX motherboards, offering space for larger, high-end boards with more expansion slots. The Cooler Master N200 supports Micro-ATX and Mini-ITX boards, which are smaller and fit into compact builds. If you need room for extensive PCIe slots or larger PCBs, the GT501 is the better choice. For smaller footprints and standard components, the N200 fits your needs. This difference defines the overall size and potential of your build.
Tower size
The GT501 is a Full-Tower case, designed for maximum internal space and component flexibility. The N200 is a Mini-Tower, prioritizing a smaller footprint that fits easily on or under a desk. Full-tower cases like the GT501 allow for extensive cable management and multiple drive bays, but they take up more floor space. Mini-towers like the N200 are easier to move and store. Your choice depends on how much desk or floor space you have available for your PC.
Radiator support
The ASUS TUF Gaming GT501 supports radiators up to 360mm in size, allowing for larger cooling loops or more efficient single-loop setups. The Cooler Master N200 supports radiators up to 240mm. Larger radiators provide more surface area for heat dissipation, which can help with high-end components. If you plan to use large liquid cooling solutions, the GT501 offers more flexibility. The N200 is suitable for standard air cooling or smaller liquid setups.
Side panel material
The GT501 features a 4mm-thick smoked, tempered-glass full view side panel, which provides a clear view of your internal components and RGB lighting. The data for the N200 does not specify the side panel material. Tempered glass is durable and offers a premium aesthetic, allowing you to showcase your build. If seeing your hardware is important to you, the GT501 has a clear advantage in visual appeal and material quality.
Weight and portability
The GT501 weighs 26.2 pounds, making it a heavy case that requires sturdy support. It includes woven-cotton carry handles to assist with transport. The N200 weighs only 9.5 pounds, making it significantly lighter and easier to move. If you frequently move your PC or need a case that is easy to handle, the N200 is more practical. The GT501 is built for stability and capacity rather than easy portability.
Which E-ATX or Micro-ATX Case Fits You
You need maximum expansion for large builds
The ASUS TUF Gaming GT501 supports E-ATX motherboards and offers seven traditional expansion slots plus vertical GPU support. Its full-tower chassis allows for extensive component upgrades. You get ample room for high-end parts, making it ideal for users who prioritize maximum connectivity and physical space for large systems.
You want a compact, portable desktop setup
The Cooler Master N200 is a mini-tower that weighs only 9.5 pounds. Its small footprint fits easily on desks. It supports Micro-ATX boards, keeping your build compact. The lightweight design and small dimensions make it practical for users who value space efficiency and easy mobility over maximum expansion slots.
You prefer premium airflow and cooling options
This full-tower case includes three 120mm fans and one 140mm rear fan, plus seven optional mounting points. It supports 360mm radiators on the top or front. The robust cooling infrastructure and included RGB fans provide superior thermal management for high-performance components, ensuring your system stays cool under heavy loads.
You need versatile storage for mixed drives
The Cooler Master N200 supports up to three 3.5-inch HDDs and four 2.5-inch SSDs within its compact frame. This flexibility allows you to mix large storage drives with fast solid-state drives. It is a practical choice for users who need diverse storage capacity without sacrificing the small size of their case.

Frequently asked questions
Can a Micro-ATX case fit an E-ATX motherboard?
No, a Micro-ATX case cannot fit an E-ATX motherboard. The Cooler Master N200 supports only Micro-ATX and Mini-ITX boards. Its compact Mini-Tower design lacks the physical space required for larger E-ATX form factors. You must choose a case with explicit E-ATX support, like the ASUS TUF GT501, to accommodate those larger boards.
What is the size difference between E-ATX and Micro-ATX cases?
E-ATX cases are significantly larger than Micro-ATX options. The ASUS TUF GT501 is a Full-Tower measuring 217 inches in height and weighing 26.2 pounds. In contrast, the Cooler Master N200 is a Mini-Tower standing 14.9 inches tall and weighing just 9.5 pounds. The E-ATX chassis requires much more desk or floor space.
Which case offers better airflow for high-end components?
Both cases support airflow needs but differ in scale. The Cooler Master N200 is designed for compact builds prioritizing airflow with its Mesh design. The ASUS TUF GT501 accommodates extensive cooling options due to its Full-Tower size. If you need maximum cooling for large E-ATX builds, the larger chassis provides more room for radiators and fans.
Does the ASUS TUF GT501 support Mini-ITX motherboards?
The provided data lists the ASUS TUF GT501 as supporting E-ATX motherboards. It does not explicitly state Mini-ITX support in the attributes. However, most E-ATX cases include backward compatibility. You should verify the manual for Mini-ITX compatibility, as the primary design focus is on larger E-ATX and ATX boards.
Is the Cooler Master N200 suitable for large graphics cards?
Yes, the Cooler Master N200 is suitable for high-end components despite its size. The verdict notes it offers GPU clearance for compact Micro-ATX builds. Its length of 17.5 inches allows for standard graphics cards. It is ideal if you want a smaller footprint while still fitting powerful hardware without the bulk of a Full-Tower case.
Which case is better for a gaming setup with many expansion slots?
The ASUS TUF GT501 is better for extensive expansion. It supports E-ATX motherboards and offers seven traditional expansion slots plus vertical GPU support. The Cooler Master N200 supports Micro-ATX, which typically has fewer slots. If you need maximum expandability for multiple drives or cards, the Full-Tower E-ATX case is the superior choice.
