This article covers Fractal Design Ridge PCIe 4.0 Black Mini-ITX対応 薄型PCケース FD-C-RID1N-11 CS8678.
Overview
The Fractal Design Ridge PCIe 4.0 Black FD-C-RID1N-11 is a slim Mini-ITX case engineered for tight spaces like living rooms or small desks. It ships with a PCIe 4.0 riser cable and supports both vertical and horizontal orientations, offering flexible placement options. Key specs include support for graphics cards up to 335mm (325mm with SATA SSD mounted), CPU coolers up to 70mm in height, and SFX/SFX-L power supplies only. The case occupies a mid-range position in the SFF market, targeting users who want a small, console-like PC that can still handle high-end gaming hardware.
Inside the box, you get two 140mm PWM fans pre-installed, along with a front I/O panel that includes one USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports, and an audio/mic combo jack. The overall build quality is typical Fractal—solid steel and mesh panels with a clean, minimalistic aesthetic.
Compatibility Guide
This case is strictly Mini-ITX only; ATX, Micro-ATX, and Mini-DTX motherboards will not fit. Power supply must be SFX or SFX-L—standard ATX PSUs are too large. Storage is limited to four 2.5-inch drives; there is no room for 3.5-inch HDDs. CPU cooler clearance is a tight 70mm, so only low-profile air coolers (e.g., Noctua NH-L12S, Scythe Big Shuriken 3) or AIO liquid coolers with an integrated pump that sits within that height are compatible. Graphics card clearance is generous for the form factor: up to 335mm length, but thickness is constrained. With the top fan installed, maximum GPU thickness is 57mm; without the fan, it expands to 82mm. Always double-check your GPU dimensions before purchasing.
Product Info
The Fractal Design Ridge PCIe 4.0 Black has been on the market since 2022 and remains a popular choice for console-sized PC builds. Pricing typically falls between ¥22,000 and ¥25,000, and it is widely available from Japanese online retailers as well as direct from Fractal's web store. The standard warranty is two years. This case comes bundled with a PCIe 4.0 riser, so you don't need to buy one separately. It sits firmly in the mid-range compact case category—more premium than budget Mini-ITX cases like the Cooler Master NR200, but less expensive than boutique options like the Louqe Ghost S1.
Best Use Cases
First, the Ridge is ideal for home theater PC (HTPC) builds. Its vertical orientation allows it to blend into an AV rack alongside a game console or streaming box, and it can easily drive a 4K TV for gaming or media playback. However, if you primarily use a desktop monitor with multiple drives, you might find the 2.5-inch-only limit frustrating.
Second, it suits users who want a compact desktop for a small workspace. The horizontal orientation makes it perfect for tucking under a monitor riser, freeing up desk surface. But if you plan to overclock a high-end CPU, the limited cooler height will be a bottleneck—consider a larger case instead.
Third, enthusiasts who want a powerful SFF gaming rig will appreciate the Ridge's GPU support. With careful GPU selection (e.g., most two-slot RTX 4070 or RX 7800 XT cards), you can build a formidable 1440p or even 4K gaming machine. On the flip side, fans of multi-GPU setups or those needing 3.5-inch storage should look elsewhere.
Things to Consider
The most critical limitation is CPU cooler height—70mm is very restrictive. Many high-performance air coolers (e.g., Noctua NH-D15, be quiet! Dark Rock Pro) are out of the question. You'll likely need to rely on low-profile coolers or an AIO liquid cooler with a small pump block. Also, the case lacks a dedicated radiator mount; only a few 120mm AIOs with a slim radiator/flat pump may fit, which limits CPU thermal headroom.
Another major consideration is GPU thickness. Modern high-end GPUs often exceed 57mm thickness (2.5+ slots), forcing you to remove the top fan to fit them. That can reduce airflow and cause higher temperatures. Make sure to check the dimensions of your chosen graphics card carefully.
Finally, the PCIe 4.0 riser is not forward-compatible with PCIe 5.0 devices without a BIOS workaround. If you pair a PCIe 5.0 motherboard/GPU with this case, you must set the PCIe slot to Gen4 in the BIOS; otherwise, you may experience instability or no display. That said, for current-generation hardware, PCIe 4.0 is still sufficient for most gaming and productivity tasks.
FAQ
Q: Can I use a standard ATX power supply in this case?
A: No, the Ridge only supports SFX and SFX-L PSUs. ATX units are too long and wide to fit inside the chassis. If you already own an ATX PSU, you will need to buy a new SFX unit, which can be more expensive per watt.
Q: Will a 360mm radiator fit?
A: There is no dedicated radiator mounting area in this case. The only option for liquid cooling is a 120mm AIO with a low-profile radiator/pump combo that stays within the 70mm CPU cooler clearance. Most 240mm or 360mm AIOs will not fit.
