Compare the ABS case for Pi 2/3/3+, the Pi Zero acrylic enclosure, and the stackable acrylic case with fan to find the right Raspberry Pi enclosure for your project.
Quick answer
Choose the Pi Zero acrylic enclosure for minimalist, low-cost protection; pick the ABS case for Pi 2/3/3+ for wall-mountable durability; or go with the stackable acrylic case with fan for cooling and visual flair.
Board compatibility is the first filter
The Raspberry Pi Zero uses a different physical layout than the Pi 2, 3, and 3+ models. The Pi Zero enclosure (HCRASP0020-22) is custom-cut for the Zero's smaller board and connector positions. The ABS case (HCRASP0019) and the stackable acrylic case are designed for Pi 2 and 3 (and the ABS case also supports 3+). If you have a Pi Zero, only the acrylic enclosure will fit without modification.
Material and protection trade-offs
ABS cases offer a sturdy, professional look and protect against accidental damage and short circuits. The ABS case for Pi 2/3/3+ is wall-mountable, making it ideal for permanent installations. Acrylic cases, like the Pi Zero enclosure and the stackable case, are more fragile but provide a clear view of the board and a modern aesthetic. The stackable case includes a 40mm fan for active cooling, which can extend the life of a Pi 2 or 3 under load.
Cost and complexity considerations
The Pi Zero acrylic enclosure is the most affordable option at a catalog comparison price of USD 0.82, reflecting its simple two-piece design. The ABS case for Pi 2/3/3+ is priced at USD 2.08, offering more robust protection. The stackable case, at USD 2.49, is the priciest but includes the fan and nine acrylic pieces for a more complex build. If you need a quick, no-fuss enclosure, the ABS case is simpler to assemble than the multi-layer stackable design.
Decision rules for choosing your Raspberry Pi enclosure
- 1. Match the case to your board model: If you have a Raspberry Pi Zero, your only option here is the Pi Zero acrylic enclosure. For Pi 2 or 3B, both the ABS case and the stackable case work. For Pi 3B+, only the ABS case is compatible.
- 2. Decide on cooling needs: If your Pi runs processor-intensive tasks (e.g., media center, retro gaming), the stackable case with its 40mm fan helps prevent thermal throttling. For light usage, the ABS or acrylic enclosures are sufficient. Check your Pi's typical temperature under load; if it exceeds 80°C, consider the fan-equipped case.
- 3. Consider mounting and access: The ABS case is wall-mountable and provides easy access to all ports. The stackable case and Pi Zero enclosure are not wall-mountable. If you need to mount your Pi on a wall or inside a project box, the ABS case is the clear choice.
- 4. Balance budget and aesthetics: The Pi Zero enclosure is the cheapest and simplest. The ABS case offers professional looks at a moderate price. The stackable case is the most expensive but delivers a unique layered look and active cooling.
Product facts at a glance
- ABS Case for Raspberry Pi 2, 3, 3+: This wall-mountable ABS case is designed for Raspberry Pi 2, 3, and 3+ and protects against accidental damage or short circuits. If you need a durable, permanent installation with easy access to connections, this case provides reliable protection without active cooling.
ABS Case for Raspberry Pi 2, 3, 3+ - Raspberry Pi Zero Enclosure (HCRASP0020-22): This simple acrylic enclosure is custom-cut for the Raspberry Pi Zero and uses two pieces with spacers for easy assembly. It's the only enclosure in this lineup that fits a Pi Zero, offering minimal protection at the lowest price point.
Raspberry Pi Zero Enclosure (HCRASP0020-22) - Stackable Raspberry Pi Case (Various Colours): This stackable acrylic case includes a 40mm fan and is designed for Pi 2 and 3B (not 3B+), with nine alternating clear and black acrylic pieces. Choose this when your Pi runs hot or you want a striking visual design, but verify your board is the 3B, not 3B+.
