Combo doesn't always mean that it's put together, mind you. My brother's wasn't, for example. It came separately boxed. But, we knew it most likely worked together well since it was bundled, plus it ends up being cheaper. The motherboard he had before this one was also a bundle, but that one already had the cpu and heatsink installed. The less I have to fumble around with the stuff, the better, in my opinion. I just want it to work. And so many times, upgrading leads to problems somewhere or another, so one less thing to worry about is fine with me.
