Okay, what happens if something fails/dies? At least it's replaceable by the user. It's very common to upgrade the RAM capacity rather than buying it all at once. Many CPUs have stuck around long enough to see GPUs replaced. Hard drives get swapped out for faster/more space.

I love the idea of component machines, but at this time of my life, I would be just fine to never have build another PC. With that, these systems of plug in the cables and go to work are appealing. Having said that, it still rubs me the wrong way on how non-upgradeable these things are.
