I'm trying to downsize my current build, which is housed in an O11 Mini V2, without replacing many of my existing components. I'm using a micro-ATX motherboard and a large Aorus RTX 5070 Master graphics card. Appearance and side-panel style don't matter to me—I mainly want the smallest practical case that can accommodate both parts. What cases should I consider, and are there any compatibility concerns I should check?

Use a parts-list compatibility site and sort cases by internal volume. Then verify the motherboard support, GPU length and thickness, CPU cooler clearance, and power-supply dimensions manually, since the smallest cases often have tight limits.
Since you don’t care about appearance, focus entirely on measurements rather than features like a glass or fish-tank layout. The GPU may require a slightly larger case than the motherboard alone would suggest.
You could also look at the NCASE M2. It’s very compact and flexible, though compatibility can be more restrictive than with the Jonsbo. The unusually large graphics card is likely to be the deciding factor, so check its exact dimensions before choosing.
The Jonsbo D32 Pro, especially the mesh version, could be worth checking. It supports micro-ATX hardware while being more compact than many traditional cases, but make sure your specific Aorus card fits the listed GPU clearance.
