The problem that I could see with a modular upgrade, Although it's quite simplified, we all know that pc's change as often as babies change diapers. You get this pc, and find out in less than a year that there's a new mobo required to get an updated chip or memory...like DDR4 (Intel is famous for this) I agree there's a huge looking cool factor with this concept, I personally do not find that it could be practical for more than a couple years. Yes...you could easily replace the main board, memory....even the cpu but is it going to be worth the extra costs for this convenience?
