This article covers Thermaltake The Tower 600 Gravel Sand 3面強化ガラスパネル採用 八角柱スタイル ミドルタワー ATX PCケース CA-1Z1-00MGWN-00 CS9172.

Overview

The Thermaltake The Tower 600 Gravel Sand is a mid-tower PC case that stands out with its octagonal design and three tempered glass panels on the front. The Gravel Sand color offers a subdued, earthy tone that blends well into most desk setups. It supports ATX, Micro-ATX, and Mini-ITX motherboards, and can be used in either vertical orientation (standard) or horizontal with an optional stand kit.
Cooling is a strong point: the case can accommodate up to 13 fans and radiators up to 420mm on the right side. This makes it suitable for high-end builds with large GPUs and custom water loops. The motherboard is mounted vertically, with the rear I/O facing upward, which is a unique layout that requires some planning for cable routing.
Thermaltake has also designed the case to work with back-connect motherboards from ASUS, MSI, and GIGABYTE, with removable panels on the rear corners for easy access to connectors.

Compatibility Guide

  • Motherboard support: ATX, Micro-ATX, Mini-ITX
  • PSU: Standard ATX, up to 220mm length
  • GPU clearance: Up to 400mm (280mm with PSU cover installed)
  • CPU cooler height: Up to 210mm
  • Storage: 1x 3.5-inch, 2x 2.5-inch (or 3x 2.5-inch)

    The vertical motherboard layout means cable routing is different from traditional cases. If you use a back-connect motherboard, the removable rear panels make it easier to plug in cables.

Best Use Cases

  • Showcase gaming builds: The three glass panels let you display RGB fans, custom water loops, and premium components. Ideal for enthusiasts who treat their PC as a centerpiece.
  • High-end hardware: With 400mm GPU clearance and 210mm CPU cooler height, you can install flagship GPUs like the RTX 4090 and large air coolers without issue.
  • Unique form factor seekers: If you're tired of standard rectangular towers, the octagonal design and optional horizontal orientation offer something different.
    Not recommended for users who need a compact footprint or who want a traditional layout without extra planning for cable management.

Things to Consider

The vertical motherboard orientation is unconventional and may require more thought during assembly, especially for cable routing and cooler orientation. The case is designed for vertical use out of the box; horizontal use requires an additional stand kit.
When using liquid cooling in horizontal mode, ensure the radiator is positioned higher than the pump to avoid air bubbles. The case is also relatively heavy at 9.7 kg, so moving it after building may be cumbersome.
At its price point, there are established alternatives from Fractal Design and Corsair that offer more conventional layouts and proven airflow. The Tower 600 is best chosen for its unique aesthetics rather than raw performance metrics.
