i've had good luck with TT AIOs, & a few of their cases are also great value for cool temps, but i'm not sure this venture into custom-loop is the right direction... not going to pull most AIO users up market, & not likely to attract many custom peeps away from EK,etc
...really wish more Mfgs would get into semi-custom water cooling; serviceable, repairable, expandable (ala Kraken G12 style GPU adapters, and extra pumps/reservoirs/lines/rad options), with easy no-drip no-leak quick disconnects.
full-cover blocks, compression fittings, hard-line tubes, etc ...all very nice stuff, but far too expensive & low ROI value/performance for most of us. at the other end of the spectrum, AIOs have to be tossed out entirely when they suffer any failure at all or even just get too old - what a waste. products somewhere in the middle would be nice!
