Best Mini-ITX Cases of 2026 — Three Picks Worth Building In

Mini-ITX has matured. The 2026 case picks are quieter, easier to build in, and meaningfully better at GPU thermals than the 2024 cohort.

At the budget tier, the Cooler Master NR200P MAX at $169 is still the easiest recommendation. The bundled SF750 PSU and 280mm AIO removes two component decisions, and the 32cm GPU clearance handles even the chunky RTX 5070 Ti AIBs.

At the premium tier, the FormD T1 v2.1 at $325 (chassis only) remains the most builder-respected sandwich case. New for 2026, the ASUS A21 at $209 is the dark-horse pick — clean front-mesh design, 360mm AIO support in the top, and surprisingly accommodating cable management for the price tier.
