Thank you very much. As this problem of Pcie or agp is just a recent spark in my curiosity, I've been across many forums which provide the pop-it-off method with pictures. It really isn't that hard of a task and I might end up having to do it, but I still kind of want to know why my section on CPUID is grayed; partly to know the version without dismantling, and partly because it doesn't seem like anyone elses section is grayed out on any other forums that i've been on which I'm not sure if I should be concerned about. In the time that I'm taking to do all this, though, I really could just take this stupid case off and quit whining.
As far as responses go, your's was informative and appreciated. I'm going to go crack this thing, then. Goodnight.
