Waveshare Aluminum Stripe Grooved Case for Raspberry Pi 5, Built-In Cooling Fan and Heatsink Pillars

The Raspberry Pi 5 runs noticeably warmer under sustained load than earlier Pi generations, making active cooling a near-necessity for any case that's going to see continuous use rather than light occasional tasks. This case builds that cooling directly into the enclosure - the grooved aluminum stripe design and internal heatsink pillars conduct heat away from the board while the built-in fan actively moves air, rather than requiring a separate fan mounted inside an otherwise passive case. That integration means one part does the job of both protecting the board and keeping it cool, instead of combining a case with a bolt-on fan accessory.
