It's the little details that separate ?good? from 'stellar?. All of the planning and detail you do can be thrown off by one mismatched connector or component. Think about it, if you have a black and gold build and have a single green USB connector, that is exactly what the eye is drawn to and it looks terribly out of place. Or maybe you have a black and green themed build, with everything matched right down to some green LED RAM. An orange Cougar fan in the rear exhaust position would look, well, not very good, and that is something as simple as a single, inexpensive fan. It's these little things, however, that put your build over the top.

Cables may be the biggest offender. Even many sleeved cables have glimpses of yellow and red at the ends, and they have a bad habit of sitting front and center of your window on PCIe connectors. Front panel audio connectors have a bad habit of trying to emulate a mismatched rainbow at the end. This is why we see the popularity of modding cables and extensions growing, as well as more people individually sleeving their own cables. Of course, this can be expensive, and/or rather tedious work that always risks breaking a connector. Wouldn't it be far simpler if we could simply buy power supplies with premium cables already included at a reasonable price?
