Probably one of the best ITX cases in 2021! Extremely easy to build, great ventilation, allows full size GPU and looks great.
The SSUPD Meshlicious Mini-ITX Mesh Case White is only 14.6 liters in size, features a full mesh panel design for increased airflow and cooling performance, supports m-ITX motherboards, radiator support at front (up to 280mm), support for up to 3 x SSD, 2 x HDD, compatible with both ATX and SFX power supplies (up to 170mm), and supports a graphics card of up to 334mm in length.

Excellent case, I pre-ordered mine on release.
Only minor issue is that you'll need to 3D print legs (to raise the height) or get Right-Angled HDMI/DP Cable or Adapters.
