Alphacool Core 100 Aurora Reservoir and VPP D5 Pump.200ml Reservoir with D5 pump (Alphacool VPP Version). Comes with a Molex to Sata cable (which was not included with original pump). All mounts and accessories are included but uses standard m3 screws and h2.5 hex wrench. It's lightly used, I would say about 6months at 50% speed before I switched to a smaller pump; has been sitting in a box ever since. Selling because I got a smaller pump, but there's nothing functionally wrong with it. Actually, it's quieter than my smaller pump, but my build needed the space.
