Thermaltake Tower 300 Gravel Sand Micro-ATX Case - Compact

In this review of the Thermaltake Tower 300 Gravel Sand Micro-ATX case, the bottom line is simple: builders who want a compact enclosure that prioritizes cooling and presentation will appreciate this chassis. The case ships with two 140mm CT fans and supports radiators up to 420mm, making it a strong choice for air- or water-cooled small-form-factor builds. With three 3mm tempered glass panels and an optional chassis stand kit for horizontal display, it balances thermal performance with visual polish for Mini ITX and Micro-ATX systems.

Key Features

• High-performance cooling: Two pre-installed 140mm CT fans and support for multiple fans and up to a 420mm radiator keep temperatures low under sustained load.
• Tempered glass panels: Three 3mm thick tempered glass panels provide a clear, unobstructed view of internal components for a premium presentation.
• Motherboard compatibility: Supports Mini ITX and Micro-ATX motherboards to accommodate a range of compact build configurations.
• Front I/O convenience: Front panel USB 3.2 Gen 2 Type-C, USB 3.0 and HD audio ports make connecting peripherals quick and modern.
• Horizontal display option: The optional chassis stand kit enables a horizontal orientation if a desk or shelf layout calls for it.

Who It's For

The Tower 300 Gravel Sand is aimed at enthusiasts building compact, visually-focused systems who still want substantial cooling headroom; it suits gamers, content creators, and hobbyist builders who plan to use midrange to high-end cooling solutions. Its tempered glass panels make it especially appealing to those who want to showcase custom cooling, RGB, or neatly routed cable work.

Those who need large E-ATX motherboards, an abundance of drive bays, or a very small budget mini-ITX rig without space for larger radiators should look elsewhere. The case balances presentation and cooling rather than maximizing raw internal expansion space.

Pros & Cons

Pros

• Strong cooling support with two included 140mm fans and up to a 420mm radiator for thermally demanding builds.
• Three 3mm tempered glass panels deliver a clean, premium look and excellent component visibility.
• Flexible orientation with an optional stand kit for horizontal display to fit varied setups.
• Modern front I/O including USB 3.2 Gen 2 Type-C adds future-proof connectivity.

Cons

• Compact Micro-ATX layout means less internal expansion room than mid-tower cases, which may limit very large multi-drive or oversized GPU configurations.
