C4Labs Zebra Bramble Cluster Fan Case for Raspberry Pi (4-Stack)

In this review the C4Labs Zebra Bramble Cluster Fan Case is evaluated for small-scale cluster builders who need a clean, stackable enclosure that cools multiple Raspberry Pi boards. The case is clearly designed for users running headless servers, labs, or compact clusters and the single biggest reason to buy it is its combination of sturdy construction and integrated cooling in a compact footprint. The reviewer found the case attractive on a desk, solid in build, and especially useful when you want to mount a 2.5' SSD on the bottom for additional storage and tidy cabling.

Key Features

• Stackable design: Holds either four or six Raspberry Pi boards so you can scale a small cluster without reworking your enclosure.
• Integrated fans: The 4-stack ships with two 50mm 5V fans and the 6-stack includes three, giving active cooling that helps maintain stable CPU temperatures.
• SSD mounting: A 2.5' SSD hard drive attaches to the bottom of the case, providing a convenient option for local storage without external brackets.
• Two finish options: Available in Black Ice or Classic Wood, letting you choose a discreet or more natural look to match your workspace.
• Designed and crafted in the US: Made in Tacoma, WA, the case reflects attention to fit and material quality for long term use.

Who It's For

The case is best for hobbyists, educators, or small lab operators who run multiple Raspberry Pi units as lightweight servers, media nodes, or development environments and want a neat, cooled, stackable solution. If you plan to mount a single Pi on a desk or need an ultra-compact single-board solution, this product is overbuilt for that purpose and a smaller enclosure makes more sense.

Assembly required means the product suits people comfortable with basic DIY and careful alignment of boards; those who prefer a fully assembled plug-and-play chassis should look elsewhere. Customers who value durable materials and a presentable shelf or desktop display will appreciate this case.

Pros & Cons

Pros

• Solid, sturdy construction that looks good on a shelf and holds boards securely.
• Active cooling with included 50mm fans reduces thermal concern for clustered Pis under load.
• Flexible capacity with 4- or 6-stack options and bottom SSD mounting for added storage.
• Quality finishes with a Black Ice option for a low-profile, professional appearance.

Cons

• Assembly can be fiddly and the included instructions are not especially clear, which may frustrate some builders.
• Removing individual Pis and precise fit can be inconsistent according to some users, so patience is required during setup.
