Most people assume building a computing cluster requires a messy web of exposed wires and precarious stacking, but the C4Labs Cloudlet Case turns high-density computing into a clean, modular art form. This clear acrylic enclosure is impressively robust, utilizing double-thick material that feels far more substantial than standard hobbyist cases.

Rolling dice directly on a tabletop often leads to chaotic bounces and accidental damage to your gaming surface. The C4Labs Mini Personal Size Gaming Compass Dice Tray solves this by providing a dedicated, compact arena for your most important rolls. I love how the artist-designed compass is laser-etched directly into the wood, creating a surface that looks incredible and stands up to heavy use. It is built from a sturdy mix of wood, acrylic, and stainless steel, making it feel much more premium than a standard felt tray. Whether you are deep in a D&D campaign or a round of Catan, the 5.5" x 7" footprint is perfect for solo play or tight spaces. It even pairs seamlessly with their tall classic dice towers for a complete tabletop setup.

Why settle for a naked circuit board when you can give your Rock64 a professional, polished home? The Zebra Black Ice case from C4Labs is a refreshing upgrade for anyone running a Pine64 media setup. I was particularly impressed by the thoughtful design choices, like the extra clearance provided for HDMI cables, which solves a common headache with tight single-board computer enclosures. It isn't just about aesthetics, though. The ventilation is well-engineered to keep things running cool, and the inclusion of three heatsinks and rubber feet makes this a complete thermal and stability package right out of the box. Knowing this was designed and manufactured right here in the USA adds a level of confidence to the build quality that is hard to find elsewhere.

Radio enthusiasts building a dedicated MMDVM hotspot need this precision-engineered enclosure to finally move away from messy, exposed wiring. The C4Labs Black Ice case is a specialized solution that integrates a 3.5" Enhanced Nextion touchscreen directly into a rugged, laser-cut housing designed for Raspberry Pi and ZUMspot boards. While the build quality feels incredibly professional thanks to the stainless steel hardware and American manufacturing, it is a high-performance kit that demands some DIY sweat equity. You should expect to perform some soldering to get the screen communicating with your setup, and if you are running a Raspberry Pi 4, you will definitely want to add a Pimoroni Fan SHIM to prevent thermal throttling. It is a sophisticated, tight-fitting shell that turns a pile of components into a legitimate piece of hardware.

Most builders assume a rugged enclosure is the final step in a project, but this C4Labs Zebra Case actually requires a bit of thermal strategy. While it offers impressive full-body coverage for your Raspberry Pi and Adafruit GPS HAT, it lacks integrated active cooling. If you are running a Pi 4B, you should definitely plan to add a Pimoroni Fan SHIM, as the internal layers are specifically designed to accommodate one. Despite that heat consideration, the build quality is excellent, featuring precise cutouts for SD card access and the critical GPS antenna port. It is a specialized, US-made solution from Tacoma that prioritizes a tight, integrated fit for your specific hardware stack.
