The TTL video was overly flamboyant due to political reasons, he did that video to make a point with Antec. But I won't go into the details, anyway the quality of the case in his video was engineered to make it seem poor. Granted the case does have a few flaws, but with a little modification you can achieve a better build geared towards lots of space and good watercooling, like my build.
Just as a further note not for one minute do I discredit your build you have done a great job there.
Just for me Antec cases have recently been a generation or two behind the likes of NZXT, Corsair and Phanteks
Shock horror! TTL is so far in Corsair's pocket he'd exaggerate the flaws in a competitor product? I am aghast.
Don't worry I appreciate this and take this into consideration when watching anything with Corsair, Asus in etc.
All I can say is, I have owned numerous cases from Antec, NZXT, Bit Fenix, Silverstone and the 750D from Corsair I have now is by far the best in nearly every department.
