This article covers Thermaltake The Tower 300 Gravel Sand 3面強化ガラスパネル採用 八角柱スタイル マイクロタワー Micro-ATX PCケース グラベルサンド CA-1Y4-00SGWN-00 CS9097.

Overview

The Thermaltake The Tower 300 Gravel Sand is a Micro-ATX PC case featuring a distinctive octagonal column design with three tempered glass panels. Despite its compact footprint, it accommodates graphics cards up to 400mm and CPU coolers up to 210mm, making it suitable for high-end builds. The unique layout places the motherboard I/O panel at the top, routing cables to the rear for maximum internal space utilization. This small-form-factor case offers impressive cooling flexibility, supporting large radiators and multiple fans. The Gravel Sand color finish gives it a natural, understated look that blends well with any desktop environment.

Compatibility Guide

This case supports Micro-ATX and Mini-ITX motherboards. It accepts standard ATX power supplies up to 220mm in length, mounted at the top. Graphics cards up to 400mm can be installed, accommodating even the largest current-generation GPUs. CPU cooler clearance is 210mm, allowing for tall air coolers or AIO pump units. Storage options include three 2.5-inch or 3.5-inch drive bays, providing flexibility for SATA SSDs and HDDs. There are four expansion slots, supporting dual-slot graphics cards in multi-GPU configurations.

Product Info

The Tower 300 Gravel Sand is a mid-range PC case from Thermaltake's The Tower series. Released in late 2024, it comes with a 3-year warranty for the Japanese market. Priced around ¥22,939, it offers excellent value compared to similar Micro-ATX cases. Cooling capabilities are extensive: the top, rear, PSU area, and right side can accommodate up to 420mm radiators, and up to eight fans can be installed. This makes it suitable for both air and liquid cooling setups. The three tempered glass panels provide a clear view of internal components, ideal for showcasing custom builds.

Best Use Cases

Gamers building compact high-end systems: Pair a Micro-ATX motherboard with a long graphics card for a clean, space-saving desk setup. The ability to mount large radiators ensures quiet and efficient cooling even under heavy loads. Enthusiasts focused on aesthetics: The three glass panels and octagonal shape highlight RGB lighting and custom cable management. An optional horizontal chassis stand kit allows for a unique horizontal layout, perfect for display builds. * Users needing a powerful secondary PC in limited space: Using a Mini-ITX motherboard further reduces the footprint. The case fits easily in a living room or home office while still offering enough expansion for gaming or creative work.

Things to Consider

This case only supports Micro-ATX and Mini-ITX motherboards; standard ATX boards will not fit. The top-mounted PSU requires careful cable management, especially with longer ATX power supplies. The horizontal stand kit is sold separately; the case ships only for vertical orientation. The front panel includes one USB Type-C port, which requires a compatible header on the motherboard. Older motherboards may lack this header, so verify compatibility before purchase.
