TechPowerUp checked out the Swiftech Maelstrom D5 X100 Reservoir
A quote from the article:
Swiftech has updated their Maelstrom reservoir series in nearly every single manner. With the use of thick glass in a rectangular form factor for the reservoir and integrated RGB lighting, it offers color options via LEDs or a coolant of your choice. Adding to this is their new MCP655-PWM pump that offers increased compatibility with PWM controllers, while retaining the reliability, performance, and quiet nature we have come to know and love from the Laing D5.Swiftech Maelstrom D5 X100 Reservoir Review
