Why do you prefer a full modular cable set up to this semi-modular ? At this price point I think semi-modular is "best". One less failure point and greater efficiency. I don't think custom cabling is a consideration for this range. I think Semi-modular should be considered best practice outside of Vanity/RGB/Bling focused lines.
For appearance sake I do think the exit point of a semi-modular "main cable" of could be made to visually match the other cables without giving up the advantages.
