Cooler Master NR200

4.6

2 sources$79.93as of Sep 27

The Cooler Master NR200 is the default Mini-ITX case recommendation in 2026, as it has been for several years, because it pairs sane thermals, generous GPU clearance, and tool-free access at a price that undercuts almost every competitor by 2-3x. Its 18.25 L footprint is the sweet spot for SFF builds: small enough to feel intentional, large enough that you're not fighting the case during install. The downside is the no-frills front I/O and SFX-only PSU mount, but neither is unusual at this price.

Strengths

— Best price-to-build-quality ratio in the entire Mini-ITX category
— 18.25 L footprint fits 330 mm triple-slot GPUs and 280 mm radiators
— Five ventilated steel panels — every face is removable for tool-free access, per Hardware Canucks

Watch-outs

— SFX power supply only, no ATX support
— Original NR200 ships without a tempered glass panel — the NR200P upgrades that, as TweakTown notes
— Front I/O is utilitarian — no Type-C 20 Gbps like the Terra

Ranked #3 in Best Mini-ITX Cases

Lian Li A4-H2O

4.0

1 source$155as of Sep 27

The A4-H2O is what you build when you've decided 11 liters is the goal and you're willing to accept the trade-offs to get there. The sandwich layout mounts the GPU behind the motherboard, the removable front and top open up surprisingly easily for a case this small, and the 240 mm AIO support is the differentiating feature against most cases in this volume class. Cable management is the dealbreaker for some builders — there's almost nothing in the way of dedicated routing. GamersNexus calls cable management the case's main flaw; everything else is praised.

Strengths

— 11 L volume — among the smallest cases that still fit triple-slot GPUs
— Designed around 240 mm AIO water cooling, with removable top bracket for radiator install, per GamersNexus
— Mesh on all four user-facing panels keeps thermals manageable despite the tight volume

Watch-outs

— Cable management is the most-cited frustration — no dedicated tie-downs or channels
— Limited drive support (no 3.5" bays) by design — NVMe-only builds are expected
— SFX power supply only, and clearance for SFX-L is tight

How they stack up

Cooler Master NR200

The NR200 is the value pick that everyone benchmarks against. 5x more; the Lian Li A4-H2O is roughly half the volume but loses out on cable management space. The Hyte Revolt 3 trades the NR200's cubic layout for a vertical tower with carry handle. The Jonsbo C6-ITX is even cheaper but compromises on triple-slot GPU clearance.

Lian Li A4-H2O

The A4-H2O is the smallest case in this round-up at 11 L vs the Cooler Master NR200's 18. 25 L and Hyte Revolt 3's 18. 4 L. 4 L), the A4-H2O trades the Terra's wood-and-aluminum finish for a stronger mesh airflow story and proper 240 mm AIO support. Not the build for first-timers — the Jonsbo C6-ITX and Cooler Master NR200 are both significantly easier to work in.
