In case my description was a little vague, I'm imagining a page much like http://en.wikipedia.org/wiki/Comparison_of_operating_systems.

IE: model name column down the left, then columns for CPU, Bus speed, slot type, RAM type/min/max etc.

And not to take over the purpose of every single page on the wiki, with detailed info on each model. More as a handy page where folks can say, "OK, I have a Comm Slot II modem, what machines does it go in?" Sort by slot type.
