There isn't a thing about that computer that Steve Jobs would have approved of.
He would approve of the idea, but I doubt Apple would release a computer looking like stacked turds. It'd be sleek, white, and have a big honking Apple logo on it somewhere. They would say it uses quantum tunnel cooling or some made-up shit.
Hey, I'm not arguing for Razer here, just upgrading certain parts as they require. Of course, if I'm forced to upgrade multiple parts due to sockets or other circumstances then I do, but otherwise I'm going to be a cheap bastard and only upgrade what I need.
Like Thork said, a computer is more or less stuck in time due to the parts you get. When I built my first computer a few years ago I thought I'd just be able to update parts one at a time, but then I needed more powerful mining cards, and then I needed PCI slots that could handle the bandwidth. This ultimately ended with getting a whole new computer, because just getting a new GPU would bottleneck at the slots, and getting a new motherboard and GPU without a new processor is impossible due to socket compatibility. In the end the only computer parts that stay the same for me are the hard drives and the case.
