Atheus,
Adhmuz' main point is that the SG10 fits a ton more in it while being a lot less in volume. Not sure why you're pursuing the "can't fit in a custom loop" tangent. Busting on water vs air cooling is also a red herring.
I agree - for a case that has the word "nano" in it, it sure isn't as small as expected from the name.
...because the whole point of this case is custom loop water cooling - as is the Define S that it's based on. If that were not part of the design, then the whole front 40% of the case wouldn't be there, or it would be filled with drive bays or something useful, not just empty space. You think they put that big empty front section of the case just because they couldn't figure out another way to fit a long graphics card? This is why I took issue with the article stopping at demonstrating its performance on air. While it's nice to know, if you're just doing air and also go out of your way to build itx, this case would be a very strange choice, because yes, if you're not actually planning to use that space for a reservoir, pump, and a big fat radiator, then it certainly isn't all that compact.
It's like looking at a pick-up truck and saying "well it's not all that compact". People buy pick-up trucks because they need the big empty bed in the back to put things in. If you don't need it, then obviously you shouldn't be looking at pick-up trucks.
