This article covers SILVER STONE PCケース ATX.
Overview
The SilverStone SST-GD09B is a slim, horizontal PC case designed to fit neatly into a home theater cabinet. Despite its compact depth of just 358mm, it supports full-size ATX motherboards and graphics cards up to 300mm long. This makes it an excellent choice for a living-room gaming rig or a powerful HTPC. The all-steel construction and understated black finish blend well with most AV equipment. It has been a staple in the HTPC community for years, offering a rare combination of small footprint and broad component compatibility.
Compatibility Guide
The GD09B accepts ATX, Micro-ATX, and even SSI-CEB motherboards. Power supply clearance is up to 220mm depth, with 180mm recommended for easier cable management. Graphics cards up to 300mm fit without issue, covering most mid-range and many high-end models. Storage options include two 3.5-inch and two 2.5-inch drives, configurable via a multi-purpose bracket. For cooling, you can install up to three 120mm fans. There is no official support for liquid cooling radiators, but some users have managed to fit a 120mm AIO with minor modifications.
Product Info
First released in 2014, the SST-GD09B remains widely available through retailers like Japan, typically priced around ¥14,980. It carries a standard one-year warranty. In terms of market positioning, it sits at the entry-to-mid level, offering exceptional value for anyone who needs a horizontal ATX case without breaking the bank. The case weighs 4.2kg, making it relatively easy to move and assemble.
Best Use Cases
This case is ideal for HTPC builders who want a full-power PC under the TV. It can house a capable gaming GPU and a standard ATX power supply, so you can play AAA titles on a big screen without compromise. It also suits users with limited desk space who prefer a horizontal layout under the monitor. Finally, budget-conscious DIY builders will appreciate the low price and broad compatibility, allowing them to reuse existing ATX components in a compact form factor. ## Alternatives
Direct competitors include the Fractal Design Node 605 and SilverStone's own GD10. The Node 605 offers a more premium aluminum front panel but costs significantly more. The GD10 is larger and supports better cooling, but also comes at a higher price. The GD09B stands out for its affordability and SSI-CEB support, making it a great choice for those on a tight budget. However, if you plan to use high-end air coolers or custom water loops, the GD10 or a traditional tower case would be more suitable.
Things to Consider
The horizontal layout inherently restricts airflow compared to a tower case. CPU cooler height is limited to roughly 130mm, so large air coolers are out of the question. There are no dedicated mounting points for liquid cooling radiators, and fitting an AIO requires creativity. Power supply depth should be kept under 180mm to avoid cable clutter. If you are building a high-TDP system with a top-tier GPU and CPU, the GD09B may struggle thermally. It is best suited for mid-range builds where quiet operation and a low profile are priorities.
