Added, and ill show you the advantage now.
Water loop, full. Removed form my P180 and has been kicking around my room for a few days.
Waterloop still full, suspended by the 2 barbs on the block alone.
Ive never had a leak and if it wasn't for fear of breaking the thing you could throw the thing around and it would still be fine.
Whoo hoo you lose like 1° over 1/2"... Worth it imo.
