The MicroATX / mini-ITX SilverStone ALTA G1M is a very interesting (and compact) chassis, featuring a vertical design and mesh sides which are ideal for a chimney effect and passive CPU cooling. Paired with the Noctua NH-P1, the mighty i9-12900 is kept at 77°C under heavy load (Power Limit set to 100W). GPU-wise is another story as orientation and location of the graphics card prevent convection to freely occur.
