What size tubing and compressions is that? It doesn't look like 1/2" ID tubes as the compresssions don't look "chunky" like they do normally with 1/2" ID. If it isn't 1/2" ID do you take a performance hit by going with smaller tubes to get that look?

One last question (interested in bitfenix cables) is how do you attach them? Are they extensions that stick onto the end of your cables? Or do they fit straight into the modular connectors/have to solder them in yourself?
