Has anyone put an older motherboard into a MDD case? I've wanted to upgrade my dual 867 to something like 1.25 GHz or higher, but it seems the MDD motherboard is different enough that it is causing problems with aftermarket upgrade boards. OR, has anyone upgraded their MDD and been satisfied with their upgrade? What about upgrading to a 2.0 GHz SINGLE processor. I love the MDD case, but want more speed. All options considered except a Mac that does NOT boot into OS9 natively. On a side note, am I the only one who likes OS9 better than OSX? (10.1.1-10.3.8) No one need reply to this. I know I'll eventually like it, but I'm tired of waiting. ;-) STeve
