Best MFF PC Cases in 2025 

Not everyone wants a full tower PC taking over their desk and with today’s compact cases, you don’t have to trade size for power. Micro form factor (MFF) cases strike a sweet balance: small enough to fit in tighter spaces, yet roomy enough for full-sized GPUs, serious cooling, and even custom loops if you plan it right.

This list highlights the best MFF cases in 2025 across different budgets and build styles – whether you’re into clean airflow, wood-and-aluminum aesthetics, or just want something compact that can still house a beast of a rig. Let’s break down what makes each one worth your time.

Best MFF Case: Top Picks  

Jonsplus i100 Pro

Quick Highlights

• Compact transparent Mini-ITX chassis
• Supports 360mm AIO, 3-slot GPUs
• Magnesium-aluminum shell, tempered glass panels
• Excellent thermals for its size
• Price – $200 – Buy Now

The i100 Pro from Jonsplus is all about high-end compact performance. Despite its compact size, it supports a full-length triple-slot GPU, a 360mm radiator, and even 166mm air coolers – a rare feat in this class. The magnesium-aluminum frame gives it a premium feel, and the tempered glass on both sides highlights internals like a showcase.

This case is ideal for users building compact, powerful systems without compromise. Despite the small footprint, airflow is solid thanks to strategic venting and support for multiple intake/exhaust setups. It’s not cheap, but it delivers premium build quality and hardware clearance that rivals much larger cases.

Pros

• Outstanding build quality
• High-end cooling and GPU support
• Elegant, compact layout

Cons

• Premium price tag
• Mini-ITX only

Fractal Design Terra

Quick Highlights

• Includes PCIe 4.0 riser
• Front I/O with USB-C
• Crafted from anodized aluminum and real wood
• Price – $180 – Buy Now

Fractal’s Terra is one of the best-looking SFF cases you can buy. Built from anodized aluminum and a genuine walnut front panel, it delivers more than just aesthetics. It fits a 2.5-slot GPU up to 322mm and includes a PCIe 4.0 riser for vertical mounting. It’s tight inside, but well thought out—adjustable compartments let you prioritize GPU or CPU space.

It’s best suited for lower-wattage CPUs and small AIOs or compact air coolers due to its limited height clearance. If you’re going for a clean desk build or a living room PC, the Terra nails both form and function, especially for GPU-first builds.

Pros

• Gorgeous materials and finish
• Smart internal adjustability
• Solid riser cable included

Cons

• Very limited CPU cooler clearance
• Tight cable routing

Lian Li A3-WD

Quick Highlights

• Modular mATX chassis
• Supports up to 360mm AIO, 415mm GPUs
• Wood front panel, DAN Cases collaboration
• Zero included fans
• Price – $90 – Buy Now

The A3-WD is a hybrid between compact tower and airflow-focused micro form factor. It supports micro-ATX and Mini-ITX boards with ease, while allowing full-length GPU clearance and a 360mm radiator. The modular design lets you reconfigure internal space depending on your cooling and storage priorities.

A wood-textured front panel adds character, and the open internal layout ensures compatibility with large GPUs like the RTX 4080 or Radeon 7900 XTX. This is a builder’s case – no fans included, but tons of flexibility for high-performance setups that still keep a modest footprint.

Pros

• Massive hardware support in under 27L
• Clean, modular interior
• Looks unique with wood styling

Cons

• No fans included
• Requires thoughtful cable management

The NR200 has become a benchmark in the MFF space for good reason. It fits large GPUs, decent AIOs, and maintains excellent airflow with its perforated panels. It’s easy to build in despite its small size – tool-free side panels, removable brackets, and cable routing space are all well-executed.

It works well for everything from mid-range gaming rigs to compact workstation builds. While it doesn’t have luxury materials or wooden accents, it nails the fundamentals – and that’s why it’s still one of the most recommended SFF cases even today.

Pros

• Great cooling and internal layout

Corsair’s 3000D Airflow blurs the line between compact tower and full ATX case—but if you’re after airflow and room to grow, it’s a top pick. It supports full-length GPUs, up to 8 fans, and radiators on top or front—great for thermal performance without stepping into huge full tower territory.

It’s ideal for those who don’t mind going slightly above “true SFF” to gain more flexibility and easier building. It also includes two fans out of the box, solid cable routing, and a clean design that works in almost any setup.

Final Thoughts

Micro form factor cases aren’t just about saving space—they’re about building smart. The Jonsplus i100 Pro and Fractal Terra lean into premium materials and tight layouts, while Lian Li’s A3-WD and the NR200 offer more flexibility for big GPUs and liquid cooling. If you’re watching your budget, the Versa H18 and G.SKILL LT1 bring great value without feeling cheap. And if you’re okay stretching into small-tower territory, the 3000D Airflow might just be the best-balanced option overall.

It all comes down to your priorities – performance, looks, footprint, or budget. There’s something here that nails each of those goals, and in 2025, compact doesn’t have to mean compromise. Let me know if you want help pairing any of these with a GPU or cooler – it’s all about finding that perfect fit.
