Thermaltake looks ok. The ringfans seems solid. But the radiator pipes is aleminium. Mixing metals is a no go when it comes to loops.
So that means if you decide to go for that. Everything have to be considered to match up with the radiators.
No brass,copper or nickel whatsoever. Perhaps nickel is ok.
They also got new RGB hardline fittings. Those look amazing. Basicly you can have clear fluid. Then change color of the loop whenever you want
Other than when it comes to quality ek is as far as i know better. but TT is functional and looks just as good. So price would have to be considered.
For me its not a option anyway since i leave in europe. Not many TT products here. But i do have a TT case and i love it
