A ventilated printed case for a Raspberry Pi running your own Bitcoin full node — whether that's plain Bitcoin Core or a node distribution like Umbrel, myNode, or RaspiBlitz.
Passive ventilation with an optional fan mount for Pi 4B / 400-style boards. The case is empty — no SD card, no node software, no pre-configured anything.
This case is a Behind the Curtain in-house design. Whatever node software you run in it — Bitcoin Core, Umbrel, myNode, RaspiBlitz — is a separate open-source project we have no control over; get it and verify it from the source, not from us.
