Vertical Octagonal Micro-ATX Chassis

The Thermaltake Tower 300 Gravel Sand is a micro-ATX and Mini-ITX case built around a vertical octagonal prism shape. Three 3 mm tempered glass panels wrap the frame to display internal hardware. Two 140 mm fans are pre-installed at the top for immediate airflow.

Builders Wanting Vertical Showcase

This case suits builders who want a tall showcase chassis with strong radiator support and the option to lay the system flat using a separate stand kit. It is not for buyers who need a standard rectangular tower that fits tight desk cubbies. It is also not for builds that require more than two pre-installed fans without purchasing extras.

420 mm Radiator Clearance on Right Side

The defining specification is support for a single radiator up to 420 mm mounted on the right panel. This length dictates the maximum all-in-one cooler size and drives the overall internal layout. If your cooling plan needs a longer radiator or multiple thick radiators simultaneously, this chassis will not accommodate it.
