Choosing a Micro-ATX vs Mini-ITX PC case depends on your space and build goals. Both the Cooler Master N200 and the SilverStone SG13B are compact options designed for smaller motherboards.

Micro-ATX vs Mini-ITX Case Comparison
Motherboard Support
The Cooler Master N200 supports both Micro-ATX and Mini-ITX motherboards. This gives you flexibility to use slightly larger boards if needed. The SilverStone SG13B is limited to Mini-ITX and Mini-DTX boards. If you plan to use a Micro-ATX motherboard, the Cooler Master is the only option. The SilverStone will not fit those larger boards. This makes the Cooler Master more versatile for different build sizes. You can choose a Micro-ATX board for more expansion slots or stick with Mini-ITX for a smaller footprint. The SilverStone forces you into the Mini-ITX form factor strictly.
Tower Size
The Cooler Master N200 is a Mini Tower measuring 14.9 inches in height. It weighs 9.5 pounds. The SilverStone SG13B is a Small Form Factor case measuring 10 inches in height. It weighs only 6 pounds. The SilverStone is significantly shorter and lighter. This makes it easier to carry and fits into tighter spaces. The Cooler Master is taller and heavier. It takes up more desk or floor space. If space is tight, the SilverStone is better. If you want a standard tower look, the Cooler Master is larger. The size difference is clear in the dimensions provided.
Radiator Support
The Cooler Master N200 supports a 240mm liquid CPU water cooling kit in the front. This allows for larger radiators for better cooling performance. The SilverStone SG13B supports only 120mm or 140mm single fan All-in-One Liquid Coolers. It cannot fit a 240mm radiator. The Cooler Master offers more cooling options for liquid systems. The SilverStone is limited to smaller radiators. If you need strong cooling for a high-end CPU, the Cooler Master is better. The SilverStone is suitable for lower power builds. The radiator support difference is significant for water cooling builds.
GPU Compatibility
The Cooler Master N200 supports graphics cards up to 355mm in length. This fits most standard and high-end cards. The SilverStone SG13B supports standard-length expansion cards up to 10.5 inches. This is much shorter. Large graphics cards will not fit in the SilverStone. You must use low-profile or short cards. The Cooler Master allows for more powerful GPUs. The SilverStone restricts your GPU choices significantly. If you plan to use a large graphics card, the Cooler Master is the clear choice. The SilverStone is only for very small cards.
Storage Capacity
The Cooler Master N200 supports up to three 3.5-inch HDDs and four 2.5-inch SSDs. This offers good storage options for data and games. The SilverStone SG13B supports 2.5-inch and 3.5-inch hard drives. The data does not specify the exact number of drive bays available. However, the smaller size of the SilverStone suggests limited storage space. The Cooler Master has a clear advantage in storage capacity. It can hold more drives without adapters. If you need lots of storage, the Cooler Master is better. The SilverStone is likely limited to fewer drives.
Choose Your Next Mini Case
You want maximum expansion in a small tower
The Cooler Master N200 supports Micro-ATX boards, offering more layout options than Mini-ITX alone. It holds up to three 3.5-inch drives and four 2.5-inch SSDs. You can fit graphics cards up to 355mm long and coolers up to 160mm high. This mini-tower size provides significantly more internal volume for components and cables.
You need the smallest possible footprint for your desk
The SilverStone SG13B is a true small form factor case. Its compact dimensions measure 12 inches wide by 10 inches high by 14 inches long. Weighing just six pounds, it is lighter and smaller than the N200. It is designed specifically for Mini-ITX and Mini-DTX motherboards to save valuable desk space.
You plan to use high-end or large graphics cards
If your GPU is long, the Cooler Master N200 is the better choice. It supports cards up to 355mm in length. The SilverStone SG13B limits expansion cards to 10.5 inches. The N200 also accommodates larger CPU air coolers up to 160mm, giving you more flexibility for powerful hardware in a compact chassis.
