Enhance and Silverstone have major disadvantages, when it comes to cabling. Not only are they not modular, but also sleeving doesn't go all the way to the case. That kind of sloppiness does not fit for expensive passive units. Even worse, on one of Silverstone's pics, insulation on one of +5V (red) wires seems to be worn off by rubbing onto casing.
If so, that is simply horrendous, as it can cause short circuits.
