The short answer

Fractal Design Terra comes out ahead by a narrow margin (4.4 vs 4.2). Fractal Design Terra is best for: builders who want a very small, premium-finish case for a 65 W-class CPU and a GPU up to 322 mm long. Read the strengths below before deciding.

Fractal Design Terra
2 sources$199.99as of Oct 11

The Fractal Design Terra is a 10.4 L sandwich-layout Mini-ITX case with anodized aluminum panels and a walnut front strip. TweakTown rated it 93% and PC Gamer scored it 92, both praising build quality and how easy it is to build in; both also flag limited cooling, since the case ships with no fans and has a single 120 mm fan position.

Strengths
  • — Hinged side panels lift off completely, giving what PC Gamer calls 'plenty of access'
  • — Sliding central wall trades CPU-cooler height (48–77 mm) against GPU thickness (43–72 mm), per PC Gamer
  • — 8 mm-thick anodized aluminum and a walnut front section, per TweakTown
Watch-outs
  • — No fans included and only one 120 mm fan position; PC Gamer lists 'limited cooling options' as a negative
  • — A 125 mm SFX-L power supply blocked the fan position in KitGuru's build
  • — Liquid cooling is impractical: TweakTown says a 120 mm AIO requires a short GPU

Lian Li A4-H2O
Ranked #4 in Best Mini-ITX Cases
Lian Li A4-H2O
1 source$155as of Oct 10

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
  • — Aluminum exterior and SPCC steel interior — premium build feel for the price
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

How they stack up

Fractal Design Terra

At 10.4 L the Terra is the smallest case on this page, just under the 11 L Lian Li A4-H2O and well under the Cooler Master NR200 (18.25 L) and Hyte Revolt 3 (18.4 L). It matches the A4-H2O's 322 mm GPU length but has one 120 mm fan mount where the A4-H2O supports a 240 mm AIO and the NR200 a 280 mm radiator.

Lian Li A4-H2O

At 11 L the A4-H2O is far smaller than the Cooler Master NR200 (18.25 L) and Hyte Revolt 3 (18.4 L) and slightly larger than the 10.4 L Fractal Design Terra. Against the Terra it adds 240 mm AIO support where the Terra has a single 120 mm fan mount; both take graphics cards up to 322 mm. The NR200 allows 155 mm CPU coolers against the A4-H2O's 55 mm.
