This is a concept for a system to cool 8x 2.5'' hard drives using a water jacket system.
The system is comprised of several CNC aluminium blocks which channel the water around the hard drives, similar to a liquid cooled internal combustion engine. Each joint is sealed with a rubber gasket. The SSDs slot into the front and connect to a PCB with power and data connections. A slot in the front allows for easy extraction of the SSDs.
