This article covers Silverstone Technology Fortress Z アルミニウム ユニボディ Mini-ITX.

Overview

The SilverStone FTZ01B Fortress Z is a slim-form-factor PC case featuring an aluminum unibody frame. Designed for Mini-ITX and DTX motherboards with an SFX power supply, it packs surprising hardware capacity into a compact footprint. The case supports graphics cards up to 13 inches (330mm) in length, thanks to an included PCI-E riser that allows horizontal GPU mounting. Targeted at users who want a powerful gaming or HTPC build in a space-constrained environment, the FTZ01B offers positive-pressure airflow for efficient cooling and dust resistance. It can be placed horizontally or vertically, giving flexibility for living room setups or desktop arrangements.

Compatibility Guide

The FTZ01B is strictly limited to Mini-ITX and DTX motherboards. Standard ATX or Micro-ATX boards will not fit. The power supply must be SFX form factor (SFX-L may work with careful cable management). CPU cooler height is restricted to 83mm, ruling out most tower air coolers. Liquid cooling is possible with a single 120mm radiator at the front. Graphics card clearance is 330mm in length and 2 slots in width. Many modern high-end GPUs exceed 2-slot thickness, so check dimensions carefully. Storage options include two 2.5-inch SSDs and one 3.5-inch HDD. No optical drive bay is provided.

Product Info

Released in 2015, the FTZ01B remains available through SilverStone's official channels. Pricing in Japan is around ¥44,000 ( reference). The case occupies a mid-to-high tier position in the slim-case market, offering premium aluminum construction and exceptional GPU support for its size. It is a direct successor to the RVZ01, refined with a more elegant all-metal exterior.

Best Use Cases

Living Room Gaming / HTPC: The slim profile fits into AV cabinets, and the ability to house a full-size GPU means 4K gaming or media editing is feasible in a console-like form factor. Space-Constrained Desktop Builders: Gamers with limited desk space who still want a discrete graphics card will appreciate the FTZ01B's compact footprint without sacrificing GPU performance. * Aluminum Enthusiasts: Builders who value aesthetics and build quality will enjoy the unibody aluminum chassis, which feels premium compared to typical steel cases.

Things to Consider

Given its age, the FTZ01B has limitations with modern high-TDP components. The 2-slot GPU restriction is increasingly problematic as newer cards adopt 2.5- or 3-slot coolers. CPU cooler height of 83mm limits you to low-profile coolers or a 120mm AIO, which may not be sufficient for high-end CPUs under sustained load. SFX PSU requirement narrows your power supply choices, and cable management is tight. A fully modular SFX unit is strongly recommended. Additionally, installing a 3.5-inch HDD may reduce available GPU length, so plan your storage layout in advance. Competitors include SilverStone's own RVZ01 and the Fractal Design Node 202. The FTZ01B offers superior build quality with its aluminum body, but falls behind in cooling expandability. For a modern build, consider newer alternatives like the Cooler Master NR200 or SilverStone Milo series, which offer better compatibility with current hardware.
