What is interesting is that a lot of old computers operated by this standard where you would have one big backplane and a lot of IO cpu's etc attached to that. I find it interesting how we have gone full circle. I do not understand what the use of modularity would be. Modern gaming rigs are already fairly modular. The only trick is that a lot of peripherals are not hot-swappable which I have trouble understanding why one (outside of the server and mainframe world of course) would want a hot-swappable gpu or cpu.
