News Gigabyte and Maingear's Project Stealth Hides All of the Cables in Your Case

Same problem you have with most custom solutions. The people this is for prioritize other aspects than home reparability. You could do what I do when I buy a custom item that I know has specific failure modes, buy the replacement parts in advance and store them. When I had a Mitsubishi 3000GT VR4 Spyder after the first roof retraction failure and trouble finding parts to repair it, I bought several of the most likely failure points parts and put them in storage. Then when it failed again, I had the failed parts rebuilt and put back in storage. It was not perfect, I still had to have custom built components machined to replace some parts I did not see as failure points. But it kept the car running and for a significantly lower cost than it would have otherwise been if I had been buying those parts at the times of the failure as they simply were not available anymore.

By bar my favorite car. 3000GT. I never owned one but it was sick. Didn't a model have all wheel steering?
 
Just one problem...how would it be possible to replace the cables especially if you have to replace the PSU?
You mean besides their attempt to lock you into their ecosystem, nothing. Pinouts will be easy to figure out and cables will be no more difficult to make than custom ones now. Cheaper really as why bother sleaving them.

This whole thing screams locked into an ecosystem that benefits only them. And I can't really see the market, people that want a really clean build are also not the people that cheap out on hardware and having choice is important to them. Maybe I'm just underestimating the prebuild market as no one posts them with pride lol
