Pros & Cons
Pros
- ✓ Refillable, expandable loop - add GPU blocks or swap tubing instead of replacing the unit
- ✓ Full copper radiator, not the aluminum fin stack used by most sealed 240mm AIOs
- ✓ Pre-filled and pre-assembled with quick-release fittings for tool-light installation
- ✓ Built from Alphacool's standard water-cooling parts, so replacements are off-the-shelf

Cons
- ✗ Refill and expansion capability only pays off if you plan to service the loop
- ✗ Pump-on-block layout puts the noise source on the CPU rather than at the radiator
- ✗ Listing does not state socket compatibility or warranty - confirm both before buying
