Personaly I'd go for the Maze3, they are pressure tested to 85psi. Swiftechs 'no leak'gaurentee is all well and good, most leaks are at the barb~hose connections. but their gaurentee ain't gonna help if its the
rad barb that leaks!...
Dont forget swiftech use that funny tube connection that requires stiff tube. how does that sit with the rest of your system?. I think its 3/8
external as well. anyone know for sure?. that ain't gonna sit well with your DDGf4 block :shrug:
Two nice blocks: DangerDen Maze3, and Overclocked PC(OCPC)'s Atlantis. the Maze3 has a copper top for $5 extra, and the atlantis has an alu top as standard. though Lexan will only crack if you change barbs alot. it can discolour and mark easy thouh
...
Swiftechs perform well, but I'm not keen on the way they make it so's you
have to use their components or hassle trying to fit others
(smacks of Microshaft to me
)
