• Compatible with any server racks in the market.
• A single 2U rack mount can hold as many as 12 Raspberry Pi 4Bs.
• Built-to-last quality: Carbon steel coated with matte black power, the quality of the material guarantees that this thing is more durable than those 3D printed plastics.
• Maximum expandability: You should not worry about not having enough Pis. Your concerns should be where to put them when you finally get there (a few dozen) and whether there’s still plenty of room left in the rack.
