Well then you might be interested to know that ChiefTec are the people who build the corsair cases (ok not fully confirmed but a lot of small give aways the majority of the body of evidence is pointing to chieftec)
Bad luck on the PSU's I've encountered a bad HX520w once it was DOA, but generally they have been solid, the move from seasonic to CWT and increasing prices have put me off however.
Also I'd look at a obsidian 700 or 800 for water cooling as that was designed with a eye to water cooling where as the 600T and 650D (which is the same internal frame) has been designed around air cooling rather than water cooling.
I'd say have a look at the coolermaster dominator 690 version 2 for a water cooled case.
Or stupidly expensive the Silverstone TJ11
http://www.scan.co.uk/products/silve...oogle+shopping the only case on the market deigned to fit 560 rads 4x140mm infact I'm pretty sure you can put two 560 rads in it.
